Abstract
5065. Riedel Akt.-Ges., J. D. Oct. 23, 1913, [Convention date]. Void. [Published under Section 91 of the Act.] Halogenized salicylic acids and homologues thereof. - 6-Halogen-1-methyl-3-oxybenzene-4- carboxylic acids are prepared for use as antiseptics by the action of halogens such as bromine and chlorine upon m-cresotinic acid in the presence or absence of solvents. According to an alternative process, p-chlor-m-cresol in the form of its sodium compound is converted into the carboxylic acid by the action of carbon dioxide under pressure. Salts of salicylic acid and its homologues halogenized in the p-position to the hydroxyl group are also prepared for use as antiseptics.
