Ethyl vinyl ether

- Sep 04, 2018-

Ethyl vinyl ether, also known as vinyl ether, has the formula C4H8O and has the structural formula H2C=CH-O-C2H5. A colorless, ethereal, flammable liquid. It is chemically active, easy to polymerize in liquid and gas phases, and is often added to industrial products to prevent polymerization. Slightly soluble in water. It has a paralytic effect on the central nervous system. It can be reacted with acrolein to synthesize 1,3-propanediol, which is an important monomer for the preparation of PTT fibers. Vinyl methyl ether, colorless liquid, easy to liquefy. Melting point -121.6 °C. Slightly soluble in water, soluble in ethanol and ether. It is easy to polymerize, so in the finished product, a polymerization inhibitor is often added. Used in the production of glutaraldehyde and polymer materials, coatings, plasticizers, adhesives, etc. The vinyl methyl ether and other monomers are copolymerized to synthesize paints, plasticizers, and modifiers such as polystyrene resins. It can be obtained by vinylation of acetylene and methanol under the action of potassium hydroxide.

The vinyl ether palsy central nervous system, its anesthetic effect is stronger than ether, so it is used as an anesthetic and analgesic in medicine. This product is also an intermediate of fine chemicals, which can be used in the production of sulfadiazine, disinfectant glutaraldehyde, polymers, coatings, etc. It can also be used to make perfumes and lubricant additives. Store in a cool, ventilated warehouse. Keep away from fire and heat. The temperature should not exceed 30 °C. Keep the container sealed. It should be stored separately from oxidants, acids, etc., and should not be mixed. Not suitable for large storage or long-term storage. Explosion-proof lighting and ventilation facilities are used. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
