Abstract
A catalyst for continuous production of 1,1,1,3-tetrachloropropane through gas-solid reaction as well as a preparation method and use thereof are provided. The catalyst includes a zero-valent iron and phosphorus co-modified carbon material which includes a carbon material as a carrier, a zero-valent iron supported onto the carrier and serving as an active component, and a phosphate functional group formed on the surface of the carbon material. The preparation method includes: co-modifying a carbon material using a ferric salt and organic phosphorus to obtain the catalyst for continuous production of 1,1,1,3-tetrachloropropane through gas-solid reaction. The present application further provides a method for continuous production of 1,1,1,3-tetrachloropropane through gas-solid reaction. The catalyst provided in the present application integrates active component zero-valent iron and auxiliary component phosphate functional group on the carbon material, thereby realizing the continuous production of 1,1,1,3-tetrachloropropane on a gas-solid fixed bed reactor.
