Description

technical field

[0001] The present invention relates to a method for continuously producing dichloropropanol and its device, in particular to a method for producing dichloropropanol from glycerol with a high conversion rate within a short residence time by controlling the feed rate to be the same as the discharge rate Continuous method for alcohol and device thereof. Background technique

[0002] Epichlorohydrin is mainly used in the production of fine chemical products such as epoxy resin and chlorohydrin rubber, which are widely used in the fields of chemical industry, light industry, transportation, medicine, and electronic appliances.

[0003] In the past, epichlorohydrin was produced by using propylene as a raw material, chlorinated with chlorine gas as a chlorinating agent, and then epoxidized to obtain epichlorohydrin. However, due to the shortage of oil, the price of propylene will increase day by day, and the by-product glycerol of biodiesel will inevitably be surp...
