BEN′ZOATE (-zo-āte). [Eng., Fr.] Syn. Ben′zoäs, L. A salt in which one atom of benzoic acid is replaced by a metal or other basic radical. The benzoates may, in general, be easily prepared by either neutralising the acid with the base, or by double decomposition. Most of them are more or less soluble in water, and crystallisable. Those of the alkalies and ammonia are very soluble, and rather difficult to crystallise. See Benzoic Acid and the respective bases.
BEN′ZOENE*. See Tuluole.
BENZO′IC ACID (-zō′-ĭk). HC7H5O2 Syn. Flowers of benzoin′; Hy′drated ben′zoyl; Acidum benzo′icum (B. P.); Acide benzoïque, Fleurs de benjoin, &c., Fr.; Benzoesäure, &c., Ger. A substance which is commonly stated to be the characteristic constituent of the two balsams. Pure oil of bitter almonds suffers gradual conversion into this acid by exposure to the air.
Prep. The acid of commerce is principally obtained from gum-benzoin, either by sublimation (dry way), or by dissolving it out by means of an alkali, or an alkaline earth in the form of a salt (moist way); but chiefly by the first method.
