Methyl formate Chemical Properties,Uses,Production


Methyl formate is the methyl ester form of formic acid. It can be used for the manufacturing of fromamide, dimethylformamide, acetic acid and formic acid. It has been proposed to be a building block in C1 chemistry (processes that convert molecules with one carbon atom such as carbon monoxide, methanol, formaldehyde and methane into organic compounds with increased carbon number). It can also be used for quick-drying finishes and a blowing agent for some polyurethane foam due to its high vapor pressure. It can also be used as an insecticide.

Chemical Properties

colourless liquid


Fumigant and larvicide for tobacco and food crops. Fire hazard is avoided by use with CO2.

General Description

A clear colorless liquid with an agreeable odor. Flash point -27°F. Less dense than water Vapors heavier than air.

Air & Water Reactions

Highly flammable. Water soluble. Reacts slowly with water to give formic acid, a corrosive material, and methanol, a flammable liquid. Both products are dissolved in the water.

Reactivity Profile

Methyl formate reacts with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated with caustic solutions. Flammable hydrogen is generated by mixing with alkali metals and hydrides.

Health Hazard

Inhalation causes irritation of mucous membranes. Prolonged inhalation can produce narcosis and central nervous symptoms, including some temporary visual disturbance. Contact with liquid irritates eyes and may irritate skin if allowed to remain. Ingestion causes irritation of mouth and stomach and central nervous system depression, including visual disturbances.

Fire Hazard

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