Procedure

The resulting product vapors were condensed to give a mixed condensate comprising butyrolactone (GBL), 1,4-butanediol (DIOL), tetrahydrofuran (THF), butanol (BUOH), and water. The condensate obtained was analyzed by gas-liquid chromatography, and it was found that 31.1 parts of butyrolactone and 64.5 parts of butanediol were produced per 100 parts of butyrolactone fed. This corresponds to 68.4% conversion of the butyrolactone and 92.3% selectivity to butanediol.
