Method for preparing 1,4-butanediol having an APHA color index of less than 30 by treating substance mixtures comprising 1,4-butanediol by distillation of the 1,4-butanediol in the presence of complex hydrides.

Method for the preparation of 1,4-butane diol having an APHA color index of less than 30

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 Br&#xf8;nsted acidity, which results in decreased production of ether byproducts.
