ABSTRACT:
p-n-Alkylbenzoic acids having high purity without containing isomers are important as intermediates for liquid crystals. The p-n-alkylbenzoic acid is produced by reacting a p-formylbenzoic acid or its ester with a ketone having the formula ##STR1## wherein R represents a C.sub.1 -C.sub.18 n-alkyl or n-alkenyl group in the presence of a basic catalyst to obtain an unsaturated ketone compound having the formula ##STR2## wherein R is defined above and X represents hydrogen atom or a C.sub.1 -C.sub.6 alkyl group, and then, hydrogenating and reducing the unsaturated ketone compound to obtain the p-n-alkylbenzoic acid having the formula ##STR3##
