Zusammenfassung:	1308894 Sulphides MOBIL OIL CORP 12 Jan 1971 [12 Jan 1970] 1442/71 Heading C2C [Also in Division C5] An organic sulphide of high combined sulphur content is prepared by sulphohalogenating an olefin or cyclo-olefin with a sulphur halide in the presence of a catalytic quantity of a C 1-4 aliphatic alcohol to form a sulphohalogenated organic intermediate, and thereafter sulphurizing and dehalogenating said intermediate in the presence of a substantial quantity of a C 1-4 aliphatic alcohol (e.g. 10-50% by weight) by treatment with an aqueous alkali metal monosulphide solution derived, by successive treatments with hydrogen sulphide and alkali metal hydroxide, from a spent aqueous alkali metal hydroxide effluent from hydrocarbon purification and having a substantial combined sulphur content. If the spent effluent contains a substantial proportion of organic compounds, the organic phase may be separated after the H 2 S treatment and before the alkali metal hydroxide treatment.
