In medicine, Ethyl vinyl ether (CAS NO.109-92-2) is used as anesthetics, analgesics, but also as intermediates for fine chemical, intermediates for sulfadiazine. It makes up the monomer of copolymer, organic synthetic materials, spices amd lubricating oil additives.
Ethyl vinyl ether (CAS NO.109-92-2) was produced by the pressurized reaction of acetylene and ethanol in the presence of potassium hydroxide catalyst.

RTECS: KO0710000
F: 19
HazardClass: 3
PackingGroup: I
HS Code: 29091900
Mildly 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.
