Document Type and Number:
WIPO Patent Application WO/2023/236741
Kind Code:
A1
Abstract:
Disclosed is a continuous preparation method for 1,1,1,2,3-pentachloropropane. 1,1,1,3-tetrachloropropane and chlorine are continuously introduced into a reactor respectively and are subjected to a reaction under the action of a solid oxide catalyst to obtain the 1,1,1,2,3-pentachloropropane. The reaction is a gas-liquid-solid three-phase reaction, the 1,1,1,3-tetrachloropropane is introduced from the top of the reactor, and the chlorine is introduced from the top or the bottom of the reactor. The reaction condition is mild and the process is simple. In addition, the process also has the advantages of less three wastes, good conversion rate of 1,1,1,3-tetrachloropropane, high product selectivity, stable catalyst, and capability of achieving continuous production and the like, and has a wide industrial application prospect.
