| Hazard Information | Back Directory | 【General Description】
A clear colorless liquid with a fragrant odor. Moderately toxic. Flash point 14°F. Vapors heavier than air. | 【Reactivity Profile】
METHYL ACETATE(79-20-9) 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(79-20-9) reactivity is consistent with other compounds of the ester group. | 【Air & Water Reactions】
Highly flammable. Water soluble. | 【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. |
