To provide a method for producing a trans-dicyclohexyl-3,3'4,4'- tetracarboxylic acid being a new starting raw material for a polyimide resin.

This method for producing a trans-dicyclohexyl-3,3'4,4'- tetracarboxylic acid such as (IR,1'S,3R,3'S,4R,4'S)-dicyclohexyl-3,3'4,4'- tetracarboxylic acid, etc., comprises reducing tetramethyl biphenyl-3,3',4,4'- tetracarboxylate with hydrogen, recrystallizing to preferentially separate an isomer of cis structure, hydrolyzing the isomer to give a cis-tetracarboxylic acid and heating the cis-tetracarboxylic acid in water at 200-250°C by using an autoclave.
