sulphotoluolamide

[Pref. sulpho-, and Eng. toluol amide.] H2 25 Chem.: CHSO2N. Formed in the same way as sulphophenylamide, and obtained in needles or lam inæ. sul-pho-vin-ic, adj . [Pref. sulpho-; English vin( yl ), and suff. -ic .] Derived from or containing sulphuric acid and vinous alcohol. sulphovinic-acid, s. [ETHYL SULPHURIC ACID.] sul-phûr, s . [Lat. sulphur, sulfur ; Sansc.sul var i ; Dut. sulfor ; Fr. souffré ; Prov. solfre , solpre; Sp.azufre ; Ital. solfo , zolfo .] 1. Chem .: Symbols. Atomic weight=32. A hexad non-metallic element, found native in many volcanic districts, and largely distributed through the min eral kingdom. It is purified by distillation in an iron still, the sulphur being received either in a brick chamber, when it is called flowers of sulphur, or condensed in the liquid state, and then cast into sticks. It occurs in several allotropic forms, namely, the octohedral, monoclinic, amorphous, and plastic varieties. It is a very brittle solid, of lemon-yellow color, tastele , almost inodorous, insoluble in water, but soluble in carbon disulphide, oil of turpentine, and benzol, and to a slight extent in hot alcohol, and has in the crystalline state a specific gravity=25. It melts at114-120°, boils at 440°, evolving an orange-colored vapor, and com bines directly with the great majority of the elements. In its chemical relations it resembles oxygen, and is interchangeable with it by double decomposition of their respective compounds. It is inflammable in air or oxygen, burning with a clear blue flame, being converted into sulphurous oxide, SO2. Various fruits, seeds, and bulbs, as radish, turnip, ., derive their flavor from oils having sulphur in their composition. 2. Engrav.: A term applied to impre ions taken by the goldsmiths of the sixteenth century from the engravings executed on plate, paxes, ., and obtained by spreading a layer of melted sulphur on the face of the plate, producing a cast in relief of the lines engraved. They are extremely rare. 3. Min .: A mineral occurring in nature in crystals belonging to the orthorhombic system, also ma ive. Hardne , 1.5-2.5; specific gravity, 2-072; luster, resinous; streak, sulphur-yellow; brittle. Occurs in magnificent crystals in the Sicilian mines, formerly near Cadiz, Spain. Found in abundance in the regions of extinct and active volcanoes, and in hydrothermal districts. ble in water, and produce deep violet coloration with ferric salts. sul-pho-săl-i-çỹ1-01', subst. [Pref. sulpho-, and Eng. salicylol.] red. sŭl-pho-sin-ap-Ic, a. [Pref. sulpho-, and Eng. sinapic.] Derived from or containing sulphur and sinapic acid.
