Ethyl acrylate is a colorless liquid. Sharp, acrid odor. The Odor Threshold is 0.000240.0009 ppm

化学的特性

colourless liquid

物理的性質

Clear, colorless liquid with a penetrating and pungent odor. Leonardos et al. (1969) and Nagata and Takeuchi (1990) reported odor threshold concentrations of 0.47 and 0.26 ppbv, respectively. Experimentally determined detection and recognition odor threshold concentrations were 1.0 μg/m3 (0.24 ppbv) and 1.5 μg/m3 (0.37 ppbv), respectively (Hellman and Small, 1974).

天然物の起源

Reported found in pineapple, yellow passion fruit and durian (Durio zibethinus).

使用

Ethyl Acrylate is a flavoring agent that is a clear, colorless liquid. its odor is fruity, harsh, penetrating, and lachrymatous (causes tears). it is sparingly soluble in water and miscible in alcohol and ether, and is obtained by chemical synthesis.

使用

Ethyl acrylate is used in the manufacture ofacrylic resins, acrylic fibers, textile and papercoatings, adhesives, and leather finish resins;and as a flavoring agent.

使用

Monomer for acrylic resins.

製造方法

By esterification of acrylic acid; by heating acetylene with HCl in alcoholic solution in the presence of Ni(CO)4; also from ethyl-3-chloropropionate passed over activated carbon at high temperature.

Aroma threshold values

Detection: 0.2 ppb

一般的な説明

A clear colorless liquid with an acrid odor. Flash point 60°F. May polymerize exothermically if heated or contaminated. If the polymerization takes place inside a container, the container may rupture violently. Auto ignition temperature 721°F (383°C) (NTP). Less dense than water. Vapors heavier than air. Used to make paints and plastics.

空気と水の反応

Highly flammable. Insoluble in water.

反応プロフィール

A flammable liquid, confirmed carcinogen. Ethyl acrylate can react vigorously with oxidizing reagents, peroxides,strong alkalis and polymerization initiators. [NTP] Ethyl acrylate reacts violently with chlorosulfonic acid [Sax, 9th ed., 1996, p. 1515]. When an inhibited monomer was placed in a clear glass bottle exposed to sunlight, exothermic polymerization set in and caused the bottle to burst. The use of brown glass or metal containers and increase in inhibitor concentration (to 200 ppm; tenfold) was recommended [MCA Case History No. 1759]. Ethyl acrylate may polymerize when exposed to light and Ethyl acrylate is subject to slow hydrolysis. Inhibitors do not function in the absence of air. Solutions in DMSO are stable for 24 hours under normal lab conditions. [NTP].

危険性

Toxic by ingestion, inhalation, skin absorption; irritant to skin and eyes. Flammable, dangerous fire and explosion hazard. Possible carcinogen.

健康ハザード

May cause irritation and burns of eyes and skin. Exposure to excessive vapor concentrations can also cause drowsiness accompanied by nausea, headache, or extreme irritation of the respiratory tract.

健康ハザード

Ethyl acrylate is a strong irritant to the eyes,skin, and mucous membranes. The liquid orits concentrated solutions can produce skinsensitization upon contact. It is toxic by allroutes of exposure. The toxicity is low inrats and mice and moderate in rabbits. Thetoxic effects from inhalation noted in animalswere congestion of lungs and degenerativechanges in the heart, liver, and kidney. Mon key exposed to 272 ppm for 28 days showedlethargy and weight loss; while exposure to1024 ppm caused death to the animals after2.2 days (Treon et al. 1949). By compari son, guinea pigs died of exposure to about1200 ppm for 7 hours. Ingestion of the liq uid may result in irritation of gastrointestinaltracts, nausea, lethargy, and convulsions
The LD50 values varied significantly indifferent species of animals. The oral LD50values in rabbits, rats, and mice are in therange 400, 800, and 1800 mg/kg, respectively. Animals administered ethyl acrylateshowed increased incidence of tumors inforestomach. However, there is no evidenceof carcinogenicity caused by this compoundin humans.

化学反応性

Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: May occur; exclude moisture, light; avoid exposure to high temperatures; store in presence of air; Inhibitor of Polymerization: 13-17 ppm monomethyl ether of hydroquinone.

安全性プロファイル

Confirmed carcinogen with experimental carcinogenic data. Poison by ingestion and inhalation. Moderately toxic by skin contact and intraperitoneal routes. Human systemic effects by inhalation: eye, olfactory, and pulmonary changes. A skin and eye irritant. Characterized in its terminal stages by dyspnea, cyanosis, and convulsive movements. It caused severe local irritation of the gastroenteric tract; and toxic degenerative changes of cardiac, hepatic, renal, and splenic tissues were observed. It gave no evidence of cumulative effects. When applied to the intact skin of rabbits, the ethyl ester caused marked local irritation, erythema, edema, thickening, and vascular damage. Animals subjected to a fairly high concentration of these esters suffered irritation of the mucous membranes of the eyes, nose, and mouth as well as lethargy, dpspnea, and convulsive movements. A substance that migrates to food from packagmg materials. Flammable liquid. A very dangerous fire hazard when exposed to heat or flame; can react vigorously with oxidizing materials. Violent reaction with chlorosulfonic acid. To fight fire, use CO2, dry chemical, or alcohol foam. When heated to decomposition it emits acrid smoke and irritating fumes. See also ESTERS.

安全性

It is an acute toxin with an LD50 (rats, oral) of 1020 mg / kg and a TLV of 5 ppm. The International Agency for Research on Cancer stated, "Overall evaluation, Ethyl acrylate is possibly carcinogenic to humans (Group 2B)." The United States Environmental Protection Agency (EPA) states, "Human studies on occupational exposure to ethyl acrylate... have suggested a relationship between exposure to the chemical(s) and colorectal cancer, but the evidence is conflicting and inconclusive. In a study by the National Toxicology Program (NTP), increased incidences of squamous cell papillomas and carcinomas of the fore stomach were observed in rats and mice exposed via gavage (experimentally placing the chemical in the stomach). However, the NTP recently determined that these data were not relevant to human carcinogenicity since humans do not have a fore stomach, and removed ethyl acrylate from its list of carcinogens." (Occupational exposure generally involves exposure that occurs regularly, over an extended period of time.)
One favorable safety aspect is that ethyl acrylate has good warning properties; the odor threshold is much lower than any level of health concern. In other words, the bad odor warns people of ethyl acrylate's presence long before the concentration reaches a level capable of creating a serious health risk.

職業ばく露

This material is used in emulsion polymers for paints, textiles, adhesives, coatings and binders; as a monomer in the manufacture of homopolymer and copolymer resins for the production of paints and plastic films

環境運命予測

Chemical/Physical. Polymerizes on standing and is catalyzed by heat, light, and peroxides (Windholz et al., 1983). Slowly hydrolyzes in water forming ethanol and acrylic acid. The reported rate constant for the reaction of ethyl acrylate with ozone in the gas phase was determined to be 5.70 x 10-18 cm3 mol/sec (Munshi et al., 1989).
At an influent concentration of 1,015 mg/L, treatment with GAC resulted in an effluent concentration of 226 mg/L. The adsorbability of the carbon used was 157 mg/g carbon (Guisti et al., 1974).

輸送方法

UN1917 Ethyl acrylate, Hazard Class: 3; Labels: 3-Flammable liquid

純化方法

Wash the ester repeatedly with aqueous NaOH until free from inhibitors such as hydroquinone, then wash it with saturated aqueous CaCl2 and distil it under reduced pressure. Hydroquinone should be added if the ethyl acrylate is to be stored for extended periods. [Beilstein 2 IV 1460.] LACHRYMATORY.

不和合性

May form explosive mixture with air. Atmospheric moisture and strong alkalies may cause fire and explosions unless properly inhibited (Note: Inert gas blanket not recommended). Heat, light or peroxides can cause polymerization. Incompatible with oxidizers (may be violent), peroxides, polymerizers, strong alkalis; moisture, chlorosulfonic acid, strong acids; amines. May accumulate static electrical charges, and may cause ignition of its vapors. Polymerizes readily unless an inhibitor, such as hydroquinone is added. Uninhibited vapors may plug vents by the formation of polymers.
