A study of the catalytic properties of synthetic zeolites in the dehydration of butane-1,4-diol

Abstract

A study of the catalytic dehydration of butane-1, 4-diol in the presence of synthetic zeolites—NaX, CaX, HNaA, HNaX, and DcX—has shown that the best catalysts for the preparation of tetrahydrofuran (THF) are HNaX and DcX. The maximum yield of tetrahydrofuran (98%) was obtained on HNaX and DcX at 240°C with a space velocity of 0.7 hr−1(ml/ml · hr).
