Spiritus Rectificatus (Br.)—Alcohol (90 Per Cent).

"A liquid containing 90 parts, by volume, of ethyl hydroxide (C2H5OH) and 10 parts, by volume, of water, obtained by the distillation of fermented saccharine liquids"—(Br. Pharm., 1898). (See Alcohol.)
SYNONYM: Rectified spirit.

"Alcohol (90 per cent) is only slightly stronger than the rectified spirit of the British Pharmacopoeia, 1885, containing, by volume, 1.35 per cent, or, by weight, 1.65 per cent, more ethyl hydroxide"—(Br. Pharm., 1898).

Diluted alcohol is official in the present British Pharmacopoeia, in four grades, containing, respectively, 70, 60, 45, and 20 per cent of ethyl hydroxide, by volume. The Spiritus Tenuior (Proof Spirit) of the British Pharmacopoeia, 1885, containing about 57 per cent of absolute alcohol, by volume, is no longer official.


King's American Dispensatory, 1898, was written by Harvey Wickes Felter, M.D., and John Uri Lloyd, Phr. M., Ph. D.
