Methylisobutyl Ketone by Direct Conversion of Acetone and Hydrogen

Abstract

Summary:Tokuyama Soda has recently developed a new process for manufacturing methylisobutyl ketone. This process is based on one-step conversion of acetone and hydrogen in vapor and liquid phases in a trickle reactor using a specially prepared bifunctional catalyst. The catalyst essentially comprises zirconium phosphate containing a small amount of finely and uniformly dispersed palladium metal. High catalytic activity and durability have been confirmed in continuous operations using a pilot plant having a capacity of 300kg a day.Besides the excellent durability of the catalyst, high productivity and simpleness of Tokuyama MI BK Process make it far more economical than the conventional process.

Research progress of catalysts for aldol condensation of biomass based compounds

“…The catalytic generation of DAA requires the catalysis of acidic or basic sites, while the dehydration of DAA to MO requires the catalysis of acidic sites, and the selective hydrogenation of MO to MIBK requires the catalysis of metal sites. [102][103][104] Therefore, the reaction is prone to excessive condensation, or non-selective hydrogenation to form by-products. Based on this, the reaction catalyst is Pd 0.1wt%/HT, which is due to the yield of MIBK is directly related to the alkalinity of the supported metal.…”
