Title:
CATALYST FOR CONTINUOUS PRODUCTION OF 1,1,1,3-TETRACHLOROPROPANE IN GAS-SOLID PHASE REACTION, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/108788
Kind Code:
A1
Abstract:
A catalyst for the continuous production of 1,1,1,3-tetrachloropropane in a gas-solid phase reaction, a preparation method therefor and the use thereof. The catalyst comprises a zero-valent iron and phosphorus co-modified carbon material, which comprises a carbon material serving as a carrier, zero-valent iron loaded on the carrier and serving as an active component, and a phosphate functional group formed on the surface of the carbon material. The preparation method comprises: obtaining a catalyst for the continuous production of 1,1,1,3-tetrachloropropane in a gas-solid phase reaction by means of co-modification with a ferrous salt and an organophosphorus. Further provided is a method for continuously producing 1,1,1,3-tetrachloropropane in a gas-solid phase reaction. According to the catalyst, the active component zero-valent iron and the auxiliary component phosphate functional group are integrated on the carbon material carrier, such that the dependence of a traditional intermittent kettle type reaction on a liquid catalytic promoter is eliminated, and the continuous production of 1,1,1,3-tetrachloropropane on a gas-solid-phase fixed bed reactor is realized.
