Part 963

Sul"phi*nide (?), n. [Sulpho- + amine + anhydride.] (Chem.) 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.

Sul"phi*on (?), n. [Sulpho- + ion.] (Chem.) 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.]

Sulph*i"on*ide (?), n. (Chem.) A binary compound of sulphion, or one so regarded; thus, sulphuric acid, H&?;SO&?;, is a sulphionide.

Sul"phite (?), n. [Cf. F. sulfite. See Sulphur.] (Chem.) A salt of sulphurous acid.

Sul"pho- (?). (Chem.) A prefix (also used adjectively) designating sulphur as an ingredient in certain compounds. Cf. Thio-.

Sul`pho*ar*sen"ic (?), a. (Chem.) Of, pertaining to, or containing, sulphur and arsenic; -- said of an acid which is the same as arsenic acid with the substitution of sulphur for oxygen.

Sul`pho*car"bon*ate (?), n. (Chem.) A salt of sulphocarbonic acid; a thiocarbonate.

Sul`pho*car*bon"ic (?), a. (Chem.) Of, pertaining to, or designating, a sulphacid, H2CSO2 (called also thiocarbonic acid), or an acid, H2CS3, analogous to carbonic acid, obtained as a yellow oily liquid of a pungent odor, and forming salts.

Sul`pho*cy"a*nate (?), n. (Chem.) A salt of sulphocyanic acid; -- also called thiocyanate, and formerly inaccurately sulphocyanide.

Ferric sulphocyanate (Chem.), a dark red crystalline substance usually obtained in a blood-red solution, and recognized as a test for ferric iron.

Sul`pho*cy*an"ic (?), a. [See Sulphur, Cyanic.] (Chem.) Of, pertaining to, derived from, or designating, a sulphacid, HSCN, analogous to cyanic acid, and obtained as a colorless deliquescent crystalline substance, having a bitter saline taste, and not poisonous.

Sul`pho*cy"a*nide (?), n. (Chem.) See Sulphocyanate.

Sul`pho*cy*an"o*gen (?), n. (Chem.) See Persulphocyanogen. [Obs.]

Sul"pho*nal (?), n. (Med.) A substance employed as a hypnotic, produced by the union of mercaptan and acetone.

Sul"pho*nate (?), n. (Chem.) A salt of sulphonic acid.

Sul"phone (?), n. (Chem.) Any one of a series of compounds analogous to the ketones, and consisting of the sulphuryl group united with two hydrocarbon radicals; as, dimethyl sulphone, (CH&?;)&?;.SO&?;.

Sul*phon"ic (?), a. (Chem.) Pertaining to, or derived from, a sulphone; -- used specifically to designate any one of a series of acids (regarded as acid ethereal salts of sulphurous acid) obtained by the oxidation of the mercaptans, or by treating sulphuric acid with certain aromatic bases (as benzene); as, phenyl sulphonic acid, C6H5.SO2.OH, a stable colorless crystalline substance.

Sulphonic group (Chem.), the hypothetical radical, SO2.OH, the characteristic residue of sulphonic acids.

Sul*pho"ni*um (?), n. [Sulphur + ammonium.] (Chem.) A hypothetical radical, SH3, regarded as the type and nucleus of the sulphines.

Sul`pho*phos"phate (?), n. (Chem.) A salt of sulphophosphoric acid.

Sul`pho*phos"phite (?), n. (Chem.) A salt of sulphophosphorous acid.

Sul`pho*phos*phor"ic (?), a. Of, pertaining to, or designating, a hypothetical sulphacid of phosphorus, analogous to phosphoric acid, and known in its salts.

Sul`pho*phos"phor*ous (?), a. (Chem.) Of, pertaining to, or designating, a hypothetical acid of phosphorus, analogous to phosphorous acid, and known in its salts.

Sul"pho*salt` (?), n. (Chem.) A salt of a sulphacid.

Sul`pho*stan"nate (?), n. (Chem.) A salt of sulphostannic acid.

Sul`pho*stan"nic (?), a. (Chem.) Of, pertaining to, or designating, a sulphacid of tin (more exactly called metasulphostannic acid), which is obtained as a dark brown amorphous substance, H&?;SnS&?;, forming a well-known series of salts.

Sul`pho*tung"state (?), n. (Chem.) A salt of sulphotungstic acid.

Sul`pho*tung"stic (?), a. (Chem.) Of, pertaining to, or designating, hypothetical sulphacid of tungsten (called also sulphowolframic acid), analogous to sulphuric acid, and known in its salts.
