Abstract: A stepwise isopropylation reaction of acetone is developed for preparation of methyl isobutyl ketone(MIBK) through acetone condensation and a recoverable Pt/C-catalyzed transfer hydrogenation of mesityloxide (MO) with isopropanol (IPA). Almost quantitative MO conversion (up to 99.9%) and excellent MIBKselectivity (up to 99.3%) could be achieved by the method. Since IPA can be obtained from propane, acheap petrochemical product, the by-product acetone (AT) generated in the reduction of MO could beeasily recovered and reused in the preparation of MO, and the Pt/C catalyst could be recycled and reused,this H2- and waste-free reaction may be a green and practical method for preparation of the useful finechemical MIBK.
