Acrylic acid Usage And Synthesis
UsesStarting material for acrylates and polyacrylates used in plastics, water purification, paper and cloth coatings, and medical and dental materials.
Basic InformationAcrylic acid (AAc, IUPAC: prop-2-enoic acid) is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus with the formula CH2=CHCO2H[1][2] which is a colorless liquid above its freezing point of 13°C ( 56°F) with a distinctive acrid odor[3][4][5]. It is corrosive to metals and tissue and prolonged exposure to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur because the polymerizaiton of acrylic acid is exothermic. The inhibitor (usually hydroquinone) can greatly reduce the tendency to polymerize. It is miscible with water, alcohol, ether, benzene, chloroform, and acetone, but incompatible with strong oxidisers, strong bases, strong alkalies and pure nitrogen. It may polymerize (sometimes explosively) when contacting with amines, ammonia, oleum and chlorosulfonic acid, iron salts and peroxides[2][4].
Preparation methods`Acrylic acid can be prepared in different ways, for example as follows:
The easiest way to prepare pure acrylic acid in the laboratory is to exchange the ester of formic acid and readily available methyl acrylate. Sulfuric acid is a good catalyst.

Acrolein can be oxidized in the liquid phase at 20-40℃ with silver or vanadium as the catalyst and methoxybenzene as the solvent which glacial acetic acid is more commonly used. It has been reported that the yield of acrylic acid can reach 65-90% based on the consumption of acrolein.

A mixture of water and 2,3 dibromopropionic acid is treated with zinc powder can obtain an aqueous solution of acrylic acid with a yield of 90%.

Acrylic acid also can be obtained by pyrolyzing sec-butyl acrylate at 500℃, or pyrolyzing ethyl acrylate at 570℃.

At 200-300℃, acrylic acid can be obtained by passing carbon dioxide and ethylene through the silica gel impregnated with iron sulfite.
ApplicationAcrylic acid is a carboxylic acid, of which the primary use is in the production of acrylic esters[2]. It has been traditionally used as the raw material for acrylic esters – methyl acrylate, ethyl acrylate, butyl acrylate and 2-ethylhexyl acrylate which were originally used to produce solvent-based acrylic resins but environmental concerns about solvent use led to the development of water-based acrylics[7]. Acrylic acid can readily react with a wide variety of organic and inorganic compounds which results in it’s considered as a very useful feedstock to manufacture many low molecular compounds, such as propionic acid, unsaturated fatty acids, heterocyclic compounds, and Diels-Alder addition products. As a vinyl compound and a carboxylic acid, acrylic acid is used widely for polymerisation, including production of polyacrylates. It is also a monomer for polyacrylic and polymethacrylic acids and other acrylic polymers[4].
Acrylic acid and esters are flammable, reactive, volatile liquids based on an alpha-, beta-unsaturated carboxyl structure. Incorporation of varying percentages of acrylate monomers permits the production of many formulations for latex and solution copolymers, copolymer plastics and cross-linkable polymer systems. Their performance characteristics—which impart varying degrees of tackiness, durability, hardness, and glass transition temperatures—promote consumption in many end-use applications. Major markets for the esters include surface coatings, textiles, adhesives, and plastics[8][9].
Polyacrylic acid which produced by acrylic acid can be further modified to produce superabsorbent polymers (SAPs) and other polyacrylic acid homopolymers or copolymers used as detergents, dispersants/antiscalants, anionic polyelectrolytes for water treatment, and rheology modifiers[7][8].
SAPs are cross-linked polyacrylates with the ability to absorb and retain more than 100 times their own weight in liquid. They have experienced very strong growth, primarily in baby diapers (nappies) and incontinence products[7][8].
A new application for SAPs is soaker pads used in food packaging. In 2007, the US Food and Drug Adminstration authorised SAPs in packaging with indirect food contact for poultry, meat, fish, fruit and vegetables[7].
Crude acrylic acid (CAA) is made by the oxidation of propylene. About 55% of the CAA is converted to acrylate esters. The remaining 45% is purified to 98–99.5% purity to glacial acrylic acid (GAA), which, in turn, is converted to polyacrylic acid, which is used to produce superabsorbent polymers (SAPs) and other polyacrylic acid copolymers. In 2016, global glacial acrylic acid consumption was estimated to account for about 45% of total crude acrylic acid consumption, of which 79% was consumed for superabsorbent polymers. Growth in GAA consumption is forecast at about 5% per year during 2016?21. Growth in demand for crude acrylic acid is forecast at 4.5% per year during 2016?21, driven by growth in superabsorbent polymers at 5.5% and acrylate esters at about 4%. SAP growth will be strongest in China and other areas of Asia, but will be much more moderate in the mature regions of North America, Western Europe, and Japan[8].
Health & Safety HazardTests involving acute exposure of rats, mice, and rabbits have demonstrated that acrylic acid has moderate acute toxicity by inhalation or ingestion, and high acute toxicity by dermal exposure. Acrylic acid is a strong irritant to the skin, eyes, and mucous membranes in humans. The liquid may cause blindness if splashed into the eye. Acute (short-term) exposure of rats to acrylic acid by inhalation has been observed to produce nose and eye irritation, lung haemorrhage, and degenerative changes in the liver and kidneys.
Some ill-health effects could happen when people exposed to acrylic acid, while people can be easily exposed to acrylic acid through direct contact with a product containing it or by inhaling it in air contaminated by a nearby plant manufacturing acrylic acid, for example, in the workplace, exposure to acrylic acid occurs primarily via inhalation and dermal contact during its manufacture or use; consumers may be exposed to acrylic acid in polishes, paints, coatings, rug backings, adhesives, plastics, textiles, and paper finishes. In addition, acrylic acid may be released in wastewater and can be also produced naturally by some species of algae. When we do not feel well, we should get medical attention immediately.
Acrylic acid is sensitive to heat and sunlight and also a fire hazard when exposed to heat or flame. The product should be stored in a segregated and approved area away from heat, sources of ignition and the container should be kept in a cool, well-ventilated area, tightly closed and sealed until ready for use. It is also very necessary to keep the product away from incompatibles such as oxidising agents, acids, alkalis, moisture.

DescriptionAcrylic acid (IUPAC: prop-2-enoic acid) is an organic compound with the formula CH2=CHCO2H. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. It is miscible with water, alcohols, ethers, and chloroform. More than one billion kilograms are produced annually.
Chemical Propertiescolourless liquid with an acrid odour
Chemical PropertiesAcrylic acid is a colorless, flammable, and corrosive liquid or solid (below 13 C) with an irritating, rancid, odor. Sinks and mixes with water; irritating vapor is produced.
UsesAn antibacterial agent.
UsesUsually used in preparing monodispersed poly (N-isopropylacryamide) (PNIPAM)/AAc microgels.And also used primarily as an intermediate in the production of acrylates.
UsesIn the manufacture of plastics.
UsesAcrylic acid is produced by oxidation of acrolein or hydrolysis of acrylonitrile. It is used in the manufacture of plastics; in paints, polishes, and adhesives; and as coatings for leather.
UsesAcrylic acid undergoes the typical reactions of a carboxylic acid and, when reacted with an alcohol, it will form the corresponding ester. The esters and salts of acrylic acid are collectively known as acrylates (or propenoates). The most common alkyl esters of acrylic acid are methyl-, butyl-, ethyl-, and 2-ethylhexyl-acrylate.
Acrylic acid and its esters readily combine with themselves (to form polyacrylic acid) or other monomers (e.g. acrylamides, acrylonitrile, vinyl, styrene, and butadiene) by reacting at their double bond, forming homopolymers or copolymers which are used in the manufacture of various plastics, coatings, adhesives, elastomers, as well as floor polishes, and paints.
Production MethodsAcrylic acid is produced from propene which is a by product of ethylene and gasoline production. CH2=CHCH3 + 1.5 O2→ CH2=CHCO2H + H2O Because acrylic acid and its esters have long been valued commercially, many other methods have been developed but most have been abandoned for economic or environmental reasons. An early method was the hydrocarboxylation of acetylene ("Reppe chemistry") : HCCH + CO + H2O → CH2=CHCO2H This method requires nickel carbonyl and high pressures of carbon monoxide. It was once manufactured by the hydrolysis of acrylonitrile which is derived from propene by ammoxidation, but was abandoned because the method cogenerates ammonium derivatives. Other now abandoned precursors to acrylic acid include ethenone and ethylene cyanohydrin.
DefinitionAn unsaturated liquid carboxylic acid with a pungent odor. The acid and its esters are used to make ACRYLIC RESINS.
General DescriptionAcrylic acid is a colorless liquid with a distinctive acrid odor. Flash point 130°F. Boiling point 286°F. Freezing point 53°F. Corrosive to metals and tissue. Prolonged exposure to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize.
Air & Water ReactionsFlammable. Soluble in water. The presence of water, due to different solubilities of the acid and inhibitor (partitioning one from the other), may initiate polymerization.
Reactivity ProfileACRYLIC ACID may polymerize violently especially when the frozen acid is partially thawed (freezing point 12°C or 53°F). Frozen acid should be melted at room temperature and the process should be well stirred. Do not use heat during the melting process [Kirk-Othmer, 3rd ed., Vol. 1, 1978, p. 330]. Corrodes iron and steel and polymerization may occur on contact with iron salts. The uninhibited acid polymerizes exothermically at ambient temperature and explodes if confined. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize. Explosive polymerization can also occur with strong bases, amines, ammonia, oleum, chlorosulfonic acid, and peroxides. Mixing with 2-aminoethanol, 28% ammonium hydroxide, ethylenediamine or ethyleneimine in a closed container causes an increase in temperature and pressure. Can react violently with oxidizing reagents and strong bases [Bretherick, 5th ed., 1995, p. 419].
Health HazardMay burn skin or eyes upon short contact. INHALATION: eye and nasal irritation and lacrimation. INGESTION: may cause severe damage to the gastrointestinal tract.
Health HazardAcrylic acid is a corrosive liquid that cancause skin burns. Spill into the eyes candamage vision. The vapors are an irritantto the eyes. The inhalation hazard is oflow order. An exposure to 4000 ppm for4 hours was lethal to rats. The oral LD50values reported in the literature show widevariation. The dermal LD50 value in rabbitsis 280 mg/kg.
Fire HazardCombustible liquid; flash point (closed cup) 54°C (130°F), (open cup) 68°C (155°F); vapor pressure 31 torr at 25°C (77°F); vapor density 2.5 (air=1); autoignition temperature 360°C (680°F). Vapors of acrylic acid form explosive mixtures with air within the range 2.9–8.0% by volume in air. Fireextinguishing agent: water spray, “alcohol” foam, dry chemical, or CO2; use a water spray to flush and dilute the spill and to disperse the vapors.
Acrylic acid may readily polymerize at ambient temperature. Polymerization may be inhibited with 200 ppm of hydroquinone monomethyl ether (Aldrich 2006). In the presence of a catalyst or at an elevated temperature, the polymerization rate may accelerate, causing an explosion. The reactions of acrylic acid with amines, imines, and oleum are exothermic but not violent. Acrylic acid should be stored below its melting point with a trace quantity of polymerization inhibitor. Its reactions with strong oxidizing substances can be violent.
Contact allergensAcrylates are esters from acrylic acid. Occupational contact allergies from acrylates have frequently been reported and mainly concern workers exposed to the glues based on acrylic acid, as well as dental workers and beauticians.
Safety ProfilePoison by ingestion, skin contact, and intraperitoneal routes. An experimental teratogen. Other experimental reproductive effects. A severe skin and eye irritant. Questionable carcinogen with experimental carcinogenic and tumorigenic data. Corrosive. Flammable liquid. May undergo exothermic polymerization at room temperature. May become explosive if confined. A fire hazard when exposed to heat or flame.
SafetyAcrylic acid is severely irritating and corrosive to the skin and the respiratory tract. Eye contact can result in severe and irreversible injury. Low exposure will cause minimal or no health effects, while high exposure could result in pulmonary edema. The LD50 is 340 mg/kg (rat, oral).
Potential ExposureAcrylic acid is chiefly used in manufacture of plastics, acrylates, polyacrylic acids, polymer, and resins; as a monomer in the manufacture of acrylic resins and plastic products, leather treatment, and paper coatings. Also, it is used as a tackifier and flocculant.
Environmental FateAcrylic acid is corrosive, and its toxicity occurs at the site of contact.
ShippingUN2218 Acrylic acid, stabilized, Hazard class: 8; Labels: 8-Corrosive material, 3-Flammable liquid
Purification MethodsIt can be purified by steam distillation, or vacuum distillation through a column packed with copper gauze to inhibit polymerisation. (This treatment also removes inhibitors such as methylene blue that may be present.) Azeotropic distillation of the water with *benzene converts aqueous acrylic acid to the anhydrous material. [Beilstein 2 H 397, 2 I 186, 2 II 383, 2 III 1215, 2 IV 1455.]
Toxicity evaluationAcrylic acid’s large-scale use and production results in its release into the environment. The most likely route of exposure is inhalation because acrylic acid has a low vapor pressure. The miscibility of acrylic acid in water combined with its low vapor pressure prevent it from accumulating in the soil. Acrylic acid that is emitted into the atmosphere is degraded photochemically by reaction with hydroxyl radicals. There is no potential for long-range atmospheric transport of acrylic acid because it has an atmospheric lifetime of 1 month.
SubstituentsAs a substituent acrylic acid can be found as an acyl group or a carboxyalkyl group depending on the removal of the group from the molecule. More specifically these are :
The acryloyl group, with the removal of the -OH from carbon-1.
The 2-carboxy ethenyl group, with the removal of a -H from carbon-3. This substituent group is found in chlorophyll..
IncompatibilitiesMay form explosive mixture with air. Light, heat, and peroxides can cause polymerization. Use MEHQ (monomethyl ether of hydroquinone) as an inhibitor. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Incompatible with sulfuric acid, caustics, ammonia, amines, isocyanates, alkylene oxides; epichlorohydrin, toluene diamine, oleum, pyridine, methyl pyridine, n-methyl pyrrolidone, 2-methyl-6-ethyl aniline, aniline, ethylene diamine, ethyleneimine, and 2aminoethanol. Severely corrodes carbon steel and iron; attacks other metals. May accumulate static electrical charges and may cause ignition of its vapors.
Waste DisposalConsult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal. Incineration. 100 500 ppm potassium permanganate will degrade acrylic acid to a hydroxy acid which can be disposed of at a sewage treatment.
