ABSTRACT:
A one-step process for selective production of methyl isobutyl ketone includes reacting in the vapor/liquid phase acetone and hydrogen at a temperature of about 100.degree. to 300.degree. C. and a pressure of about 100 to 1000 psig, in the presence of a modified ZSM-5 catalyst having a molar ratio of SiO.sub.2 /Al.sub.2 O.sub.3 from about 20:1 to 680:1, the catalyst being prepared by treating a ZSM-5 zeolite with an organic acid having a pKa of 2 to 5, ion-exchanging or impregnating the ZSM-5 zeolite with a cation selected from the group consisting of palladium cation, platinum cation, copper cation and nickel cation, and activating the resultant catalyst in a reducing atmosphere.
