Abstract: Provided are catalysts suitable for the production of tetrahydrofuran from 1,4-butanediol. Also provided are methods of use of these catalyst, as well as catalyst systems. The catalysts described herein contain only Lewis acidity, but not Brønsted acidity, which results in decreased production of ether byproducts.

Abstract translation: 提供适合于从1,4-丁二醇生产四氢呋喃的催化剂。 还提供了这些催化剂以及催化剂体系的使用方法。 本文所述的催化剂仅含有路易斯酸度，但不包括布朗斯台德酸度，其导致醚副产物的产生减少。
