BENZENE, an aromatic hydrocarbon, also called benzol, or phenyl hydride, dis- covered in 1825 by Faraday in the liquid condensed during the compression of oil gas. In 1849,, it was found in coal tar by C. B. Mansfield, who lost his life while experimenting with it on Feb. 25, 1855. Aniline is produced from it, which again is the source of the celebrated modern dyes. It is obtained from the more vol- atile portion of coal tar oil. It is also formed by distilling benzoic acid with lime. Benzene is a thin, colorless, strong- ly refracting liquid; it boils at 82°. It dissolves fats, resins, iodine, sulphur, and phosphorus; sp. gr., 0.885. BENZOATE OF SODA, a preserva- tive used in the manufacture of food products. The use of it in a quantity not greater than one-tenth of 1 per cent, is permitted by the Federal Government, but its use among packers of food has gradually been abolished.
