Methyl acetate Chemical Properties,Uses,Production

Chemical Properties

colourless liquid with a pleasant odour

Chemical Properties

Methyl acetate is a colorless liquid with a fruity odor.

Uses

Solvent for nitrocellulose, acetylcellulose, and many resins and oils; manufacture of artificial leather.

General Description

A clear colorless liquid with a fragrant odor. Moderately toxic. Flash point 14°F. Vapors heavier than air.

Air & Water Reactions

Highly flammable. Water soluble.

Reactivity Profile

Methyl acetate presents a fire or explosion hazard when exposed to strong oxidizing agents. Emits irritating fumes and acrid smoke when heated to decomposition, [Lewis, 3rd ed., 1993, p. 826]. Methyl acetate reactivity is consistent with other compounds of the ester group.

Hazard

Flammable, dangerous fire and explosion risk, explosive limits in air 3–16%. Irritant to respiratory tract. Headache, dizziness, nausea, eye damage (degeneration of ganglion cells in the retina).

Health Hazard

(Very similar to those of methyl alcohol, which constitutes 20% of commercial grade.) Inhalation causes headache, fatigue, and drowsiness; high concentrations can produce central nervous system depression and optic nerve damage. Liquid irritates eyes and may cause defatting and cracking of skin. Ingestion causes headache, dizziness, drowsiness, fatigue; may cause severe eye damage.

Fire Hazard

Behavior in Fire: Vapor is heavier than air and may travel a considerable distance to a source of ignition and flash back.

Fire Hazard

Flash Point (°F): 22 ℃; 14 ℃; Flammable Limits in Air (%): 3.1-16; Fire Extinguishing Agents: Dry chemical, alcohol foam, carbon dioxide; Fire Extinguishing Agents Not To Be Used: Water may be ineffective;Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Vapor is heavier than fire and may travel a considerable distance to a source of ignition and flash back; Ignition Temperature (°F): 935; Electrical Hazard: Data not available; Burning Rate: 3.7 mm/min.

Chemical Reactivity

Reactivity with Water Reacts slowly to form acetic acid and methyl alcohol; the reaction is not violent; Reactivity with Common Materials: No reaction; 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 several routes. A human systemic irritant by inhalation. A moderate skin and eye irritant. Mutation data reported. Dangerous fire hazard when exposed to heat, flame, or oxidizers. Moderate explosion hazard when exposed to heat or flame. When heated to decomposition it emits acrid smoke and fumes. See also ESTERS.

Potential Exposure

Methyl acetate is used as a solvent in lacquers and paint removers; and as an intermediate in pharmaceutical manufacture.

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, including 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 medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

Shipping

UN1231 Methyl acetate, Hazard Class: 3; Labels: 3-Flammable liquid.

Purification Methods

Methanol in methyl acetate can be detected by measuring its solubility in water. At 20o, the solubility of methyl acetate in water is ca 35g per 100mL, but 1% MeOH confers complete miscibility. Methanol can be removed by conversion to methyl acetate, by refluxing for 6hours with acetic anhydride (85mL/L), followed by fractional distillation. Acidic impurities can be removed by shaking with anhydrous K2CO3 and distilling. An alternative treatment is with acetyl chloride, followed by washing with concentrated NaCl and drying with CaO or MgSO4. (Solid CaCl2 cannot be used because it forms a crystalline addition compound.) Distillation from copper stearate destroys peroxides. Free alcohol or acid can be eliminated from methyl acetate by shaking with strong aqueous Na2CO3 or K2CO3 (three times), then with aqueous 50% CaCl2 (three times), saturated aqueous NaCl (twice), drying with K2CO3 and distilling it from P2O5. [Beilstein 2 IV 122.]

Incompatibilities

Vapor may form explosive mixture with air. A Strong reducing agent. Incompatible water, acids, nitrates, strong oxidizers; alkalis. Attacks some plastics. Attacks many metals in presence of water. Reacts slowly with water, forming acetic acid and methanol. Decomposes in heat; on contact with air, bases, strong oxidizers; UV-light; possible fire and explosion hazard

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.
