Abstract

108,938. Terrisse, H. Oct. 4, 1916. Oxybenzoic acids.-A mixture of isomeric sodium or potassium oxybenzoates is obtained by heating mixtures of the three cresols with caustic alkali and oxidizing-agents (oxides of copper, lead, manganese, barium, iron, &c.). A mixture of isomeric oxybenzoic acids is obtained by acidifying the mixture of alkali salts. Phenol is prepared (1) by heating the abovementioned mixture of alkali oxybenzoates in a stream of carbon dioxide at, say, 300‹ C., or (2) by heating the above-mentioned mixture of free oxybenzoic acids in a solvent or medium, for example anthracene oil, at, say, 250‹ C.
