Ethyl vinyl ether Usage And Synthesis

Chemical Properties

Colorless liquid. Extremely reactive, can be polymerized in liquid or vapor phase. Slightly soluble in water (0.9% by weight). Commercial material contains inhibitor to prevent premature polymerization. Often stored underground to minimize vapor losses.

Uses

Copolymerization, intermediate.

General Description

A clear colorless low-boiling liquid (35-36°C) with an ether-like odor. Flash point below -50°F. May polymerize exothermically if heated or contaminated. If polymerization takes place inside a container, the container may rupture violently. Less dense than water and slightly soluble in water. Hence floats on water. Vapors are heavier than air.

Air & Water Reactions

Highly flammable. Slightly soluble in water. Tends to form explosively unstable peroxides when exposed to oxygen.

Reactivity Profile

Ethyl vinyl ether is a very dangerous fire and explosion hazard when exposed to heat or flame. Undergoes autooxidation with formation of peroxides in the air. Can react vigorously with oxidizing materials. Undergoes explosive polymerization in contact with methanesulfonic acid [Eaton, P. E. et al., J. Org. Chem., 1972, 37, p. 1947].

Hazard

Carcinogen.

Health Hazard

INHALATION OR INGESTION: Excitement followed by unconsciousness and respiratory paralysis. CNS depression. EYES: May cause irritation and transient injury to cornea. SKIN: Prolonged contact can cause tissue defatting and dehydration leading to dermatitis.

Fire Hazard

Behavior in Fire: Explosive hazard

Safety Profile

Mddly toxic by ingestion. Mutation data reported. A skin irritant. A very dangerous fire and explosion hazard when exposed to heat or flame; can react vigorously with oxidizing materials. To fight fire, use alcohol foam, foam, CO2, dry chemical. Explosive polymerization is catalyzed by methane sulfonic acid. When heated to decomposition it emits acrid smoke and irritating fumes. See also ETHERS.

Purification Methods

It usually contains polymerization inhibitors (usually amines, e.g. triethanolamine) which can be removed by fractional distillation. Redistil it from sodium. [Beilstein 1 IV 2049.] LACHRYMATORY.
