Patent ID: 8304589

Claim:
A process of making a chlorinated hydrocarbon by obtaining a saturated compound represented by the following general formula (1′), comprising: an addition reaction step comprising adding carbon tetrachloride to an unsaturated compound represented by the following general formula (0) in a liquid-phase reaction system in the presence of an iron-phosphate catalyst, wherein: the iron-phosphate catalyst is prepared in the reaction system by adding iron and a phosphate to the reaction system; the whole amount of iron and part of the phosphate are added before the start of the reaction, and the remaining phosphate is added during the addition reaction step; and an amount of the phosphate to be added before the start of the reaction is not less than 0.0005 mole based on 1 mole of carbon tetrachloride in use, and not more than 70% of a total amount of the phosphate, CCl 2-m H m ═CCl 2-p H p (0) CCl 3 —CCl 2-m H m —CCl 3-p H p (1′) wherein m is 1 or 2, and p is an integer of 0 to 2, with the proviso that m≧p.
