Claim 7:
8. The preparation method according to claim 5, comprising:
heating a third mixture comprising the carbon material and the organic phosphorus to 600-1000° C. at the temperature raising rate of 5° C./min-10° C./min in the inert atmosphere to be roasted for 1-4 h to obtain a phosphorus modified carbon material; and
sufficiently contacting the phosphorous modified carbon material with a solution containing the ferric salt for 4-6 h, and adding a reducing agent in the inert atmosphere to at least reduce iron ions into the zero-valent iron, so as to obtain the catalyst for continuous production of the 1,1,1,3-tetrachloropropane through the gas-solid reaction; the reducing agent comprises sodium borohydride and/or potassium borohydride.
