The invention relates to a process of making a chlorinated hydrocarbon compound represented by the following general formula (1') through an addition reaction step in which carbon tetrachloride is added 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 in the above addition reaction step is prepared in the reaction system by adding iron and a phosphate to the reaction system; and 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 proceeding of the above addition reaction.
CCl2-mHm=CCl2-pHp (0)
CCl3-CCl2-mHm-CCl3-pHp (1')
(in the above formulas, m is 1 or 2, and p is an integer of 0 to 2, with the proviso that m ≧ p.)
