Procedure

Example 2 was repeated using this catalyst, except that the liquid feed to the vaporizer was a 1:1 mixture of butyrolactone and 1,4-butanediol, the hydrogen pressure was maintained at 900 psig. and the LHSV was 0.1. A 98% conversation of butyrolactone with 97% selectivity to butanediol was obtained.
