This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1867 edition. Excerpt: ...behind; it is soluble OXIDE or ANTIMONY. 471 without residue in sulphuret of ammonium. The quinque sulphuret of anti mony is given in doses of 1 to 1 grain. This soluble sulphuret, as used by Hnfelaud, was an uncertain preparation, containing sulphuret of antimony and calcium, sulphate and autimoniate of lime. It was prepared by exposing to a red heat a mixture of carbonate of lime, sulphur and sulphuret of, or metallic, antimony. V No double sulphuret with calcium has yet been obtained resembling the foregoing antimonio-sulphuret of sodium. Duflos proposes to mix intimately l-part of Liebig's kermes with 4 parts of sulphuret of calcium, by which process a brownish powder is obtained, almost entirely soluble in water, and decomposed by acids into sulphuretted hydrogen, and a bright red sulphuret of antimony. It is a mixture of the two snlphnrets with oxide of antimony, and has no claims to the rank of a chemical compound. It has been used in various skin diseases, &.c., in larger doses than the other antimonials. Antimonii Chloridum. SbCl, = 226.7. (Butter of Antimony.) In accordance with the Prussian Pharmacopoeia, this preparation is made by dissolving 1 lb. of black sulphuret of antimony in 4 lbs. of crude muriatic acid. These proportions are nearly those of our Pharmacopoeia, in the preliminary process for oxide of antimony. Sulphurctted hydrogen is evolved, which makes it necessary to operate in the open air, or conduct the gas into water or a chimney. After filtration, it is evaporated to 1 1b., and a mixture added of 2 lb. muriatic acid, and 11 lb. water. It is a colorless or yellowish liquid, sp. gr. 1.4, free from arsenic and lead, and is decomposed by water, oxide of antimony with some chloride being precipitated;...show more
