Methacrylonitrile Chemical Properties,Uses,Production

Chemical Properties

CLEAR COLOURLESS TO VERY SLIGHTLY YELLOW LIQUID

Uses

This study reports the toxicity and metabolism of Methacrylonitrile (MeAN) in normal male Sprague-Dawley rats and those pre-treated with caffeine, alcohol or both. These results suggest that caffeine inhibited and alcohol enhanced toxicity and metabolism of MeAN.

General Description

A clear colorless liquid. Less dense than water. Flash point 55°F. Boiling point 195°F. Very be toxic by ingestion, inhalation and skin absorption. Used to make plastics and coatings.

Air & Water Reactions

Highly flammable. Soluble in water.

Reactivity Profile

METHACRYLONITRILE is a colorless, flammable, toxic liquid. Explosive in the form of vapor when exposed to heat, flame or sparks. When heated to decomposition Methacrylonitrile emits toxic fumes of nitrile and oxides of nitrogen [Lewis, 3rd ed., 1993, p. 829].

Health Hazard

A lacrimator (causes tearing); an insidious poison which causes delayed skin reactions. Very readily absorbed through skin. Highly toxic.

Fire Hazard

Methacrylonitrile evolves flammable concentrations of vapor at temperatures down to 55.04F. Thus, at room temperatures, flammable concentrations are liable to be present. Toxic fumes of nitrogen oxides are released when the material burns. Also, the chemical will explode due to its tendency to polymerize violently. Avoid heat. Hazardous polymerization may occur.
