Butyric Acid

Butyric Acid, a volatile fatty acid discovered by Chevreul among the products of the decomposition of butter. Its formula is now written C4H802. Butyric acid has been found ready formed in human perspiration, in flesh juice, guano, excrements, putrid yeast, bad cider, dung heaps, accumulations of decomposing organic matter, in cod liver oil, and in beetles; and it is the substance which gives the disagreeable smell to rancid butter. It combines with bases to form salts, and also exists as butyric anhydride. It is a colorless, mobile liquid, of a peculiar offensive odor, having an acid taste and highly caustic property, and a specific gravity of 0-96. It can be prepared in a great variety of ways; among others, from butter, sugar, and by the action of hydriodc acid on succinic acid. Bromo-buty-ric acid, butyric aldehyde, and butyric chloride have been prepared, but they possess little practical importance.
