Source

From Crude Carbolic Acid by agitation with warm concentrated solution of Soda, heating to 3380 F.; 170° C., solution and treatment with Hydrochloric Acid. After being agitated with Sodium Chloride, digested with Calcium Chloride, it is distilled between 3360 and 3740 F.; 168.8° and 1900 C, and crystallized.

Characters

Colorless, interlaced or separate, needle-shaped crystals, or a white crystalline mass, sometimes acquiring a reddish tint, having a somewhat aromatic odor, and, when copiously diluted with water, a sweetish taste with a slightly burning after-taste. Treated with about 8 per cent. of water, it becomes fluid; the crystals are very hygroscopic, and hence soon become semifluid on exposure to air; it has a faintly acid reaction and coagulates albumin. Solubility. - Slowly in about 15 to 20 parts of water; freely in Alcohol, fats and oils. Solution in water is more easily made if an equal part of Glycerin is added.

Dose, 1/2 to 1 gr.; .03 to .06 gm.
