Ethyl vinyl ether is a colorless flammable liquid with active chemical reaction properties. Easily polymerizes in liquid or gas phases, and industrial products contain polymer inhibitors to prevent polymerization. The vapor pressure of 57.05 kPa / 20 ℃; Flash point - 45 ℃; Melting point - 115.3 ℃; Boiling point 35.6 ℃; Solubility: Slightly soluble in water, soluble in acetone, benzene, carbon tetrachloride and other organic solvents; Density: relative density (water =1)0.75; Relative density (air =1)2.5; 2. Stability; Danger marker 7(low flash point flammable liquids); Main applications: as chemical intermediates. Ethylene ether (CH2= Choc2H5) is a colorless flammable liquid with active chemical reaction properties. Easily polymerizes in liquid or gas phases, and industrial products contain polymer inhibitors to prevent polymerization. Relative density (D20) 0.7589. Boiling point 35 and 36 ℃. Melting point - 115.8 ℃. Viscosity (20℃) 0.22 MPa ·s. Refractive index (N20) 1.3767. Flash point -45.5℃, spontaneous ignition point 201.66℃. Slightly soluble in water, only 0.9% (by weight). The explosion limit in the air is 1.7-28% (volume) vinyl ether paralyzes the central nervous system, its anesthetic effect is stronger than diethyl ether, so it is used as an anesthetic and analgesic in medicine. The product is also the intermediate of fine chemicals, can be used in the production of drugs sulfadiazine, disinfectant glutaraldehyde, polymers, coatings, etc. It can also be used for making spices and lubricating oil additives. ; In medicine, it is used as an anesthetic and analgesic, as an intermediate of fine chemicals, as an intermediate of sulfadiazine, as monomer of copolymers and as raw materials for organic synthesis, and can make spices and lubricating oil additives, etc.
Environmental impact :
Health hazard : Invasion route: inhalation, ingestion and transdermal absorption.
Health hazards: after inhalation or oral, first excited, followed by confusion, respiratory paralysis. Vapor irritates respiratory tract and may cause corneal injury. The liquid can irritate the skin slightly.
Chronic effects: Liver damage may result from repeated exposure. Long-term skin contact, due to the degreasing effect and dermatitis. 
Toxicological data : Acute toxicity: LD506153mg/kg(rat oral)
Hazardous characteristics: the vapor and air form explosive mixture, in case of open fire, high heat easily combustion explosion. Reacts strongly with oxidizing agents. Potentially explosive peroxides can be produced by exposure to air or light. Its steam is heavier than air, can be diffused to a considerable distance in a lower place, in case of fire source led back combustion. In case of high heat, polymerization reaction may occur, resulting in a large amount of heat release, resulting in container rupture and explosion accidents.
Combustion (decomposition) products: carbon monoxide, carbon dioxide.
