Title:
METHOD FOR PREPARING 1,1,1,3-TETRACHLOROPROPANE
Document Type and Number:
WIPO Patent Application WO/2022/165623
Kind Code:
A1
Abstract:
Disclosed is a method for preparing 1,1,1,3-tetrachloropropane, comprising: reacting the raw materials containing carbon tetrachloride and ethylene in the presence of a first catalyst and a second catalyst to obtain the 1,1,1,3-tetrachloropropane, wherein the first catalyst comprises a carrier and an active component supported on the carrier; the active component comprises nano zero-valent iron; and the second catalyst comprises an ester compound. A supported iron catalyst is used in the preparation method, which can significantly improve the problem of easy agglomeration when only commercially available iron powder is used as a catalyst, and can also increase the specific surface area of the iron, which is conducive to the progress of the reaction.
