Propyl acetate Chemical Properties,Uses,Production

Description

Propyl acetate, also known as propyl ethanoate, is an organic compound with a molecular formula of C5H10O2. It is a clear and colourless liquid with with a mild fruity odor. It is highly flammable with a flash point of 14°C and a flammability rating of 3. It is highly miscible with all common organic solvents (alcohols, ketones, glycols, esters) but has only slight miscibility in water. Propyl acetate is found in apple and formed by the esterification of acetic acid and 1-propanol (known as acondensation reaction), often via Fischer–Speier esterification, with sulfuric acid as a catalyst and water produced as a byproduct. It is primarily intended as a solvent in the coatings and printing inks industries. It is widely used in fragrances and as a flavor additive due to its odor. It also acts as a good solvent for cellulose nitrate, acrylates, alkyd resins, rosin, plasticizers, waxes, oils and fats.

Chemical Properties

Propyl acetate has a fruity (pear–raspberry) odor with a pleasant, bittersweet flavor reminiscent of pear on dilution.

Chemical Properties

colourless liquid with a strong odour

Chemical Properties

n-Propyl acetate is a colorless liquid with a mild, fruity odor. The Odor Threshold is 70 milligram per cubic meter and 2.8 milligram per cubic meter (New Jersey Fact Sheet).

Occurrence

Reported found in apple, apple juice, apricot, banana, black currants, guava, grapes, melon, peach, pears, pineapple, plum, strawberry, tomato, vinegar, wheat and rye bread, feta cheese, Gruyere cheese, domiati cheese, yogurt, beef fat, beer, cognac, bourbon and malt whiskey, cider, grape wines, cocoa, potato chips, honey, passion fruit, starfruit, fig, prickly pear, jackfruit, litchi, sake, loquat, mountain papaya, arrack, nectarine and pepino fruit.

Uses

n-Propyl acetate is used as a solvent forcellulose derivatives, plastics, and resins;in flavors and perfumes; and in organicsynthesis.

Uses

manufacturing flavors, perfumes. Solvent for resins, cellulose derivatives, plastics.

Definition

ChEBI: An acetate ester obtained by the formal condensation of acetic acid with propanol.

Preparation

By direct acetylation of propyl alcohol.

Aroma threshold values

Detection: 2.7 to 11 ppm. Aroma characteristics at 1.0%: pungent, solventlike ethereal, fruity lift, green banana sweet with an apple and tropical fruit nuance.

Taste threshold values

Taste characteristics at 10 to 15 ppm: bubble gum estery, fruity, ethereal, tutti-frutti, banana and honey.

General Description

A clear colorless liquid with a pleasant odor. Flash point 58°F. Less dense than water, Vapors are heavier than air.

Air & Water Reactions

Highly flammable. Slightly soluble in water.

Reactivity Profile

Propyl acetate is an ester. Propyl acetate is colorless, highly flammable liquid, moderately toxic. Dangerous fire hazard when exposed to heat, flame, sparks, or strong oxidizers. When heated to decomposition Propyl acetate emits acrid smoke and irritating fumes [Lewis, 3rd ed., 1993, p. 1093].

Hazard

Flammable, dangerous fire risk, explosive limits in air 2–8%. Eye and upper respiratory tract irritant.

Health Hazard

Contact with skin and eyes causes no serious injury. High vapor concentrations will be irritating and will cause nausea, vomiting, and dizziness, with final loss of consciousness.

Health Hazard

The acute toxicity of n-propyl acetate islow in test animals. The toxicity, however,is slightly greater than ethyl acetate andisopropyl acetate. Exposure to its vaporsproduces irritation of the eyes, nose, andthroat and narcotic effects. A 5-hour expo sure to 9000- and 6000-ppm concentrationsproduced narcotic symptoms in cats andmice, respectively (Flury and Wirth 1933).A 4-hour exposure to 8000 ppm was lethalto rats. Ingestion of the liquid can cause narcotic action. A high dose can cause death. Adose of 3000 mg/kg by subcutaneous admin istration was lethal to cats. The liquid maycause mild irritation upon contact with skin
LD50 value, oral (mice): 8300 mg/kg.

Fire Hazard

Flash Point (°F): 58 ℃, 65 ℃; Flammable Limits in Air (%): 2.0-8.0; Fire Extinguishing Agents: For small fires use carbon dioxide or dry chemical. For large fires, use alcohol foam; Fire Extinguishing Agents Not To Be Used: Water may be ineffective; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 842; Electrical Hazard: Not pertinent; Burning Rate: No data.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Chemical Reactivity

Reactivity with Water No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Safety Profile

Moderately toxic by intraperitoneal and subcutaneous routes. Mildly toxic by ingestion and inhalation. Human systemic effects by inhalation: lachrymation, cough. A skin irritant. A narcotic at high concentrations. Isopropyl acetate is slightly less narcotic than normal propyl acetate. A flammable liquid and dangerous fire hazard when exposed to heat, flame, or oxidizers. Explosive in the form of vapor when exposed to heat or flame. Can react vigorously with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes.

Potential Exposure

Propyl acetate is a used as a solvent for plastics and cellulose ester resins; perfume ingredient; component of food flavoring. It is also used as a chemical intermediate.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, includ- ing resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medi- cal attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.

Shipping

UN1276 n-Propyl acetate, Hazard Class: 3; Labels: 3-Flammable liquid.

Purification Methods

Wash the ester with saturated aqueous NaHCO3 until neutral, then with saturated aqueous NaCl. Dry it with MgSO4 and fractionally distil it. [Beilstein 2 IV 138.]

Incompatibilities

Contact with nitrates, strong oxidizers; strong alkalis; strong acids; may pose risk of fire and explosions. Attacks plastic.

Waste Disposal

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
