trisulphone Chem.
(traɪˈsʌlfəʊn)
[f. tri- 5 + sulphone.]
A compound in which carbon radicals are linked to other carbon radicals by the intervention of three SO2 groups, the sulphur atoms being directly joined to the carbon atoms; e.g. triethylsulphonemethylmethane, C(CH3)(SO2.C2H5)3; trisulphone acetone, (CH3)2C:{ob}SO2-C(CH3)2{cb}2:SO2. So trisulphonic (traɪsʌlˈfɒnɪk) a., in trisulphonic acid, trisulphonic amide, trisulphonic chloride, etc., compounds of three SO2.OH, SO2.NH2, SO2.Cl, etc., groups with a trivalent element or radical, the sulphur being directly joined to the element or carbon of the radical; e.g. amine-trisulphonic acid, N(SO2.OH)3; benzene-trisulphonic acid, C6H3(SO2.OH)3; benzene-trisulphonic chloride, C6H3(SO2Cl)3; triˈsulphonate, a salt of trisulphonic acid.
