Abstract
1462894 Sulphur monochloride STAUFFER CHEMICAL CO 14 Oct 1974 [15 Oct 19731 44373/74 Heading C1A Sulphur monochloride is recovered from a liquid mixture containing the monochloride and CCl 4 by contacting the mixture with a substantially dry, inert (as defined) gas at a temperature between 75 and 150‹ C. to strip the CCl 4 from S 2 Cl 2 . The inert gas is defined as a gas inert to the S 2 Cl 2 at the process temperature and may be N 2 or air with moisture contents usually not more than 1000 p.p.m. The process may be operated continuously in a counter current contacting zone or it may be operated batchwise. Suitable plant for operating the process is shown in the Figure where CCl 4 is formed in zone 10 by reacting CS 2 with Cl 2 , the liquid reaction products leaving zone 10 through line 3 to the distillation column 20 where a crude CCl 4 product containing sulphur mono-and dichloride is separated from a crude S 2 Cl 2 product, the former being removed via line 7 and the latter product (containing 2-20% CCl 4 ) removed as an underflow via line 12 into the stripping column 30. The substantially dry, inert gas is passed counter current to the liquid S 2 Cl 2 -CCl 4 mixture in column 30, the S 2 Cl 2 product so obtained and usually containing less than 0À5% CCl 4 is removed through line 17.
