Sulphocarbolate of Sodium [Na(C6H5)SO4.Aq] is in brilliant, clear, rhombic prisms. The salt is very soluble in water. This salt can be administered as a medicine in doses of 20 to 60 gr.; it is slowly decomposed in the textures, carbolic acid being evolved. It thus

becomes a very simple means of obtaining the beneficial effects of the administration of this antiseptic without the difficulties and dangers which attend it in its uncombined irritant and caustic form. It has proved of great service in the treatment of infectious diseases. Administered in the severest cases of diphtheria, malignant scarlet fever, typhoid, erysipelas, &c., the remedy has proved of extreme value.

Sulphocarbolate of Zinc [Zn(C6H5SO4)2] is chiefly employed in solution as a lotion. By high surgical authorities it is considered to answer all the purposes of the antiseptic dressing of carbolic acid. It is inodorous, and has very slight irritating action.

The Sulphocarbolates of Potassium [KC6H5SO4] and Ammonium [NH4C6H5SO4] are also brilliant crystals; they are freely soluble, administered with the greatest ease, and have been used with success as remedial agents.

SULPHOCYAN′OGEN. A well-defined salt radical, containing sulphur united to the elements of cyanogen. Its compounds are the sulphocyanides, most of which may be formed by directly saturating hydrosulphocyanic acid with the oxide or hydrate of the base; or, from the sulphocyanide of potassium and a soluble salt of the base, by double decomposition.

SULPHOFORM. Syn. Sulpoformum. An oily liquid obtained by distilling one part of iodoform with three of sulphide of mercury.

SULPHOPHE′NIC ACID. A synonym of sulphocarbolic acid. See Sulphocarbolates.

SULPHOVIN′IC ACID. C2H5HSO4. Syn. Sulphethylic acid; Acidum sulphovinicum, L. This substance is formed by the action of heat on a mixture of alcohol and sulphuric acid; it is the intermediate product which is developed in the preparation of ether. The salts are called sulphovinates or sulphothylates.

SUL′PHUR. [Eng., L.] Syn. Brimstone; Soufre, Fr. An elementary substance. That of commerce is chiefly imported from Sicily and Italy, and is a volcanic production.
