  • Process for the production of gamma-butyrolactone
    Patent number: 5118821
    Abstract: A process for producing gamma-butyrolactone by catalytic hydrogenation of maleic anyhydride in the liquid phase with hydrogen, at a high temperature and under pressure, in the presence of a catalyst comprising nickel and palladium deposited on a support, wherein said support is a silica based support having a very high specific surface area , the value of which may range from 50 m.sup.2 /g, preferably from about 100 m.sup.2 /g to about 800 m.sup.2 /g and more.Very high conversion rates of 90-98 mole % and excellent selectivities to gamma-butyrolactone of 95 to 97 mole % are achieved by the process.
