Preparation method
The direct hydration method of epichlorohydrin is a pressurized non catalytic hydrolysis method. Epoxy propane and water at 150 N, 160 ℃, 0.78-0 Produced by direct hydration under a pressure of 98MPa, the reaction product is evaporated and distilled to obtain the finished product.
The indirect hydration method of epichlorohydrin is prepared by indirectly hydrating epichlorohydrin with water using sulfuric acid as a catalyst. The reaction equation is the same as above.
Direct catalytic oxidation of propylene.  
purpose
It is a raw material for unsaturated polyester resin, epoxy resin, polyurethane resin, as well as plasticizers, surfactants, emulsifiers, and demulsifiers. In the food industry, it is used as the solvent of essence and food pigment, tobacco wetting agent, mildew inhibitor, fruit ripening preservative, pharmaceutical excipient, etc. It can also be used as an antifreeze, heat carrier, and lubricant for food machinery.
