Abstract
Methyl isobutyl ketone is produced in a one-step process by contacting acetone and hydrogen at a temperature of from about 50.degree.-200.degree.C and a pressure between 50-100 atm, preferably 60-100 atm, in the presence of a catalyst composed of a cation exchange resin having from 0.001 to 0.1 weight percent of a noble metal distributed in monoatomic form therein.
