HALOCARBON HYDROGENOLYSIS |
| 摘要 |
Halocarbons such as CCl2F2, CF3CFHCl or CF3CFCl2 which contain chlorine and/or bromine are contacted with hydrogen in the presence of silicon carbide and/or a metal selected from aluminum, molybdenum, titanium, nickel, iron or cobalt (or their alloys) at temperatures of 350 DEG to 700 DEG C and pressures of 0 to 1000 psig to obtain a product wherein at least one chlorine or bromine in the starting material has been replaced by hydrogen. |
