PURPOSE:To suppress formation of olefin, by reducing a halogenated carbon containing at least one Cl with a mixed gas of H2 blended with N2, Ar, HF, etc., as a reducing agent in the presence of a reduction catalyst such as element of platinum group. CONSTITUTION:A halogenated carbon shown by the formula (1<=n<=3, 1<=x<=8, 0<=y<=7, 1<=x+y<=8) is reduced with a mixed gas of H2 blended with 1-99V% (preferably 10-90V%) at least one selected from CO2, N2, Ar, HCl, HF, krypton, xenon and sulfur hexafluoride) as a reducing agent in the presence of a reduction catalyst (e.g. Pd-C) at 50-30 deg.C while suppressing formation of olefin. When a gas such as CO2, N2 or Ar which is inert in a reducing atmosphere and has relatively small adsorption energy on the surface of the catalyst is added to the raw material system, dehydrohalogenation reaction preferentially occurs but suppressing effects on formation of olefin are produced. |
