Northeast Planning Propylene Oxide ECH Project

[China Epoxy Network (China Epoxy Industry Online)News on April 22, 2009: Recently a plant in Northeast China is planning an ECH (Epichlorohydrin) project, with the goal of building 20,000 A ton/year propylene oxide production plant.
This project uses propylene oxide as a raw material.
Under the catalysis of trilithium orthophosphate, propylene oxide is selectively isomerized to allyl alcohol, and allyl alcohol and chlorine are used to synthesize dichloropropene.
Alcohol, dichloropropanol is saponified by Ca(OH)2 to epichlorohydrin, and the finished product is obtained by rectification.
According to experts from the China Epoxy Industry Association ( the production process was first successfully developed by the French Le Pont Company.
During the production process, there will be about 10% side reactions during isomerization, but both propionaldehyde and acetone are organic chemical products.
To produce 20,000 tons of epichlorohydrin, it needs to consume 0.
93×2=18.
6 million tons of chlorine, and 0.
75×2=15,000 tons of propylene oxide.
The route to produce epichlorohydrin from propylene oxide raw materials is the first, but there is no problem in the process, the key is to depend on the market and economic benefits.
