Butyl vinyl ether 111-34-2

Physical and chemical properties Highly flammable. Slightly soluble in water; soluble in ethanol and ether. When exposed to oxygen, ethers tend to form unstable peroxides. Ethyl, isobutyl, ethyl tert-butyl and ethyl tert-amyl ethers are particularly dangerous in this regard. Ether peroxides can sometimes be observed depositing on containers or along the surface of liquids in the form of transparent crystals. Chemical properties Colorless liquid. Melting point -92°C, boiling point 93.8°C, relative density 0.7888 (20/4°C), refractive index 1.4026, flash point -9°C. Soluble in alcohol and ether, slightly soluble in water.
Uses This product is used in organic synthesis and can be used for polymerization and copolymerization to produce polyvinyl ethers for coatings, additives, plasticizers, etc. Uses Organic synthesis raw materials, used for polymerization, production of polyvinyl ethers for coatings, adhesives, additives, plasticizers, etc. Uses This product is mainly used in organic synthesis, etc. Production method (1) Obtained by the reaction of acetylene with butanol. This method requires less equipment and has high selectivity. (2) Obtained by the reaction of acetaldehyde and n-butanol. This method of acetal cleavage is also a common process for vinyl ethers. Another newer method is to react alcohol, ethylene and oxygen in the presence of palladium chloride-copper chloride catalyst to obtain vinyl ether.
