Process for the preparation of trans, trans-muconic acid by reacting a glyoxalacetal with ketene in the presence of an acid catalyst and hydrolyzing the .beta., .beta.'-dialkoxy-adipic acid-alkylester formed with alkali. By this new process trans, trans-muconic acid is easily obtained in better yield, which compound is an important intermediate for the production of 1,4-naphthalene-dicarboxylic acid esters.
