Epichlorohydrin Use and Manufacturing
Methods of Manufacturing
Its preparation method uses propylene as raw material, chlorination at 500°C to produce chloropropene, and chloropropene reacts with hypochlorous acid at a temperature of 25-35°C to obtain 2, 3-dichloropropanol and 1, 2-dichloropropene Alcohol, and then add 20% lime milk to the mixture for saponification, and the reaction temperature is 45-55°C to obtain epichlorohydrin.

Uses
Mainly used to prepare glycerin, epoxy resin, chlorohydrin rubber, polyether polyol, is an important raw material for the production of glycerol and glycidol derivatives, and also used as a solvent; used as an organic solvent, epichlorohydrin is a rodenticide The intermediate of Ganfu is also the intermediate of epoxy resin, synthetic glycerin and other chemical products. Epichlorohydrin is an intermediate of synthetic glycerin, and also the main raw material of epoxy resin, nitroglycerin explosive, glass fiber reinforced plastic, and electrical insulation products. And used as a mixture of cellulose ester, resin and cellulose ether. It is also a raw material for the production of surfactants, medicines, pesticides, coatings, adhesives, ion exchange resins, plasticizers, glycerin derivatives, glycidol derivatives and chlorohydrin rubber. Various epoxy resins made with epichlorohydrin and bisphenol A as the main raw materials have the characteristics of high adhesion, low shrinkage, chemical corrosion resistance, and good stability. They are widely used as coatings, adhesives, and reinforcements. Materials and casting materials, etc. The epichlorohydrin rubber produced with epichlorohydrin as the raw material is a new type of rubber. It is not easy to swell in common oils and common solvents, and has greater flexibility in the presence of low temperature without plasticizers. It is superior to nitrile and chlorine Some unique functions of butyl and butyl rubber.
