Abstract
Phenols are prepared from salts of sulphonic acids by treatment with steam and calcium hydroxide in a process in which the reaction mixture is prepared by the action of quick-lime on the aqueous sulphonate followed by drying, if necessary. Other salts, e.g. potassium chloride, may be added to the reaction mixture. Phenols mentioned are cresols, poly-phenols, e.g. resorcinol, and naphthols. In the examples: (3) phenol is prepared by the process from sodium or potassium benzenesulphonate. Specifications 554,878 and 666,589 are referred to.
