Acetoacetic Acid → Acetic Acid

참여 물질

반응 단계

The tube reactor is charged with 88.1 grams of Linde 13X zeolite (150 pellets, pretreated at 200° C. with a tetrahydrofuran-acetic acid vapor mixture) and maintained at 190°-230° C. while 50.0 grams of 1,4-butanediol diacetate and 60 ml. of water are copassed, as in Examples 1-3, over a 1 hour period. The effluent is recycled three times until the diacetate is essentially converted. Quantitative glpc analysis of the final effluent shows the presence of 0.4 grams of butanediol diacetate (1% recovery), 9.5 grams of tetrahydrofuran (47% yield) and 30.4 grams of acetic acid (89% yield). A considerable amount of low boiling material is produced using this method.
