| Carbon Sulphidoselenide, CSSe, was obtained by Stock and Willfroth by striking an electric arc under carbon disulphide between a graphite cathode and an anode containing 17.5 parts of graphite to 100 of selenium. It is an intensely yellow liquid smelling of onions; its density is 1.979, melting-point - 85° C., boiling-point 84° C., and μ20/D 1.7349. It is decomposed by light, or on long keeping at atmospheric temperature. With alcoholic sodium ethoxide it forms sodium mono-selenoxanthate, SeC(SNa)(OC2H5). |
