Abstract

PURPOSE:To readily obtain the titled high-purity compound useful as a raw material for polymers and intermediate for liquid crystal compounds in high yield in one step, by subjecting a 4-(4-hydroxyphenyl)-cyclohexanecarboxylic acid as a raw material to dehydrogenation reaction. CONSTITUTION:4-(4-Hydroxyphenyl)-cyclohexanecarboxylic acid obtained by nitration, hydrogenation, diazotation and hydrolysis of 4-phenyl-cyclohexane carboxylic acid or reacting 4-(4-methoxyphenyl)-cyclohexanecarboxylic acid with hydrobromic acid is subjected to dehydrogenation reaction in the liquid phase in the presence of a dehydrogenation catalyst, such as Pd/C, in an amount of normally 0.001-0.2g atom expressed in terms of metallic atoms thereof based on 1mol. above-mentioned compound, preferably in the coexistence of a hydrogen acceptor (which may also be used as a solvent), such as alpha- methylstyrene, at 180-450 deg.C and the catalyst is then separated. The aimed compound is subsequently separated by a method, such as crystallization.
