ethyl vinyl ether usage and synthesis |
chemical properties |
colourless liquid with an ether-like odour |
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]. |
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 |
