Abstract

1,231,991. Producing pure phenols from crude phenols. PHENOLCHEMIE G.m.b.H. 13 Jan., 1969 [13 Jan., 1968], No. 1957/69. Heading C2C. A process for the production of phenols substantially free of ketones, from crude phenols obtained by the dissociation of hydroperoxides of alkylaromatic hydrocarbons in the presence of acids, comprises contacting the liquid or vaporous crude phenols at temperatures of between 45‹ and 200‹ C. with fixed bed catalysts consisting of macro-reticular ionexchangers and containing active sulphonic acid groups or analogous active acid groups, and distilling the reaction product.
