Abstract

1314278 Trimethyl hydroquinone BADISCHE ANILIN- & SODA-FABRIK AG 7 Aug 1970 [8 Aug 1969] 38173/70 Heading C2C In a process for the manufacture of trimethyl hydroquinone by reducing trimethyl p-quinone with hydrogen in the presence of a hydrogenation catalyst and an organic solvent, the reaction is carried out using an aliphatic alcohol of from 3 to 5 carbon atoms as solvent and at a temperature of from 60‹ to 180‹ C. In the examples a palladium on silica gel catalyst and numerous solvents are employed.
