Document Type and Number:
Japanese Patent JPS5441560
Kind Code:
B2
Abstract:
An aliphatic gamma-dicarboxylic compound which is a precursor for hydrogenation into a corresponding gamma-butyrolactone is caused to contact hydrogen in the presence of a hydrogenation catalyst prepared by intimately combining nickel, molybdenum, barium and/or thallium thereby to produce the gamma-butyrolactone. The addition of barium and/or thallium is original and highly advantageous in that the resulting hydrogenation catalyst has high effectiveness in the production of gamma-butyrolactones and has a long serviceable life, being acid resistant.
