Methyl acetate Chemical Properties,Usage,Production

Chemical Properties
colourless liquid with a pleasant odour
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.
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.
