Creosotum

Creosote

Creosote.—A mixture of phenols, chiefly guaiacol and creosol, obtained during the distillation of wood-tar, preferably of that derived from the beech.

An almost colorless, yellowish or pinkish, highly refractive, oily liquid, having a penetrating smoky odor and a burning, caustic taste; usually becoming darker in tint on exposure to light. Specific gravity, not below 1070 at 15° C. (59° Fahr.). Soluble in about 150 parts of water at 15° C. (59° Fahr.), but without forming a perfectly clear solution. With 120 parts of hot water it forms a clear liquid, which on cooling becomes turbid from the separation of minute oily drops. Soluble in all proportions in absolute alcohol, ether, chloroform, benzine, carbon-disulphide, acetic acid, and fixed and volatile oils.

A combination of creosote and tincture of iodine is used successfully by inhalation. The method is simple: To a cup of hot water on a table add a few drops of the mixture, and, as the fumes arise, by means of a paper cone or shield they should be directed to the mouth or nose. Successive deep inspirations should then be made.

Creosote is neutral or only faintly acid to litmus-paper. Dose, τη ij—τη v.
