ABSTRACT:
Provided is a method for the production of tetrahydrofuran (THF) from 1,4-butanediol (BDO) using a zirconium sulfate (Zr(SO4)2.nH2O) catalyst. The method of the present invention can achieve high-yield production of tetrahydrofuran via a simple and low-risk production process by dehydration of 1,4-butanediol in the presence of a zirconium sulfate catalyst.
