| organic compounds | vinyl methyl ether, also known as methoxyethylene, methyl vinyl ether and vinyl methyl ether, belongs to organic compounds and has anesthetic effect, it is a colorless flammable gas at room temperature, with special odor and easy to liquefy. Molecular weight 58.08. Structure: CH2 = CH-O-CH3. Melting Point -123 °c. Boiling point 8. The relative density of 0.7694 (5.7/4 deg C). Refractive index 1.3947. Flash point -51 °c. Soluble in ethanol, ether, insoluble in water. Sweet taste. Polymerization is easy, and therefore polymerization inhibitors are often added to the finished product. From acetylene and methanol in the role of potassium hydroxide, vinyl reaction occurs in the system. Ethylene methyl ether and other monomers are copolymerized to synthesize modifiers such as coatings, polymer materials, binders, plasticizers and polystyrene resins. A water-soluble resin, polyvinyl methyl ether-maleic anhydride copolymer adhesive, which can be obtained by copolymerizing vinyl methyl ether with maleic anhydride. The appearance of white powder at room temperature, soluble in warm water or cold water, and ethylene glycol, amines and some inorganic salt reaction and gelation, become water insoluble, have a higher polarity, can bond rubber, steel, aluminum, polystyrene and nitrocellulose, etc. vinyl methyl ether is dissolved in water or organic solvent by ionic polymerization to obtain polyvinyl methyl ether adhesive. This product can be used for bonding rubber, aluminum, steel, polystyrene, nitrocellulose and cellophane. |
| Application | methyl vinyl ether is mainly used in the production of glutaraldehyde and polymer materials, coatings, plasticizers, adhesives, etc. |
