Title
Direct synthesis of MIBK from acetone over Pd/NaX catalysts
Abstract

The one-step synthesis of MIBK from acetone in gas phase was studied over palladium catalysts on NaX zeolite (1 and 3 wt% of Pd). A greater selectivity to MIBK was observed for a H2/acetone ratio of 6.2. Although increasing the reaction temperature caused an increase of the selectivity to condensation products, the temperature for which the selectivity to MIBK was maximum was the lower one (523 K). Decreasing the reduction temperature from 633 to 573 K for PdNaX enhanced the hydrogenation activity and decreased MIBK selectivity. Selectivities to MIBK as high as 80% were obtained.

Graphical abstractThe one-step synthesis of MIBK from acetone in gas phase was studied over palladium catalysts on NaX zeolite (1 and 3 wt% of Pd) at different H2/acetone ratios, reaction temperatures and reduction temperatures. Selectivities to MIBK as high as 80% were obtained. It was also clear that Pd hydrogenates preferentially the CC double bonds against CO double bonds.Figure optionsDownload full-size imageDownload as PowerPoint slide
