PROCESS FOR THE PREPARATION OF TRANS, TRANS-MUCONIC ACIDAbstract of the Disclosure-Process for the preparation of trans, trans-muconic acidby reacting a glyoxalacetal with ketene in the presence of anacid 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 yeild, whichcompound is an important intermediate for the production of1,4-naphthalene-dicarboxylic acid esters.
