Defn: Of, pertaining to, or designating, a sulphonic acid obtained, as a blue solution, by dissolving indigo in sulphuric acid; — formerly called also cerulic sulphuric acid, but properly called indigo-disulphonic acid.
SULPHINE
Sul"phine, n. (Chem.)
Defn: Any one of a series of basic compounds which consist essentially of sulphur united with hydrocarbon radicals. In general they are oily or crystalline deliquescent substances having a peculiar odor; as, trimethyl sulphine, (CH3)3S.OH. Cf. Sulphonium.
SULPHINIC
Sul*phin"ic, a. (Chem.)
Defn: Of, pertaining to, or designating, any one of a series of acids regarded as acid ethereal salts of hyposulphurous acid; as, methyl sulphinic acid, CH3.SO.OH, a thick unstable liquid.
SULPHINIDE
Sul"phi*nide, n. Etym: [Sulpho- + amine + anhydride.] (Chem.)
Defn: A white or yellowish crystalline substance, C6H4.(SO2.CO).NH, produced artificially by the oxidation of a sulphamic derivative of toluene. It is the sweetest substance known, having over two hundred times the sweetening power of sugar, and is known in commerce under the name of saccharine. It has acid properties and forms salts (which are inaccurately called saccharinates). I. Remsen.
SULPHION
Sul"phi*on, n. Etym: [Sulpho- + ion.] (Chem.)
Defn: A hypothetical radical, SO4, regarded as forming the acid or negative constituent of sulphuric acid and the sulphates in electrolytic decomposition; — so called in accordance with the binary theory of salts. [Written also sulphione.]
