The production capacity of acetone is excess in China at present. Conversion of acetone into high-value products with huge market demands is of practical value. Methyl isobutyl ketone (MIBK) is an important industrial intermediate with very broad applications and large market requirement. Thus, there are tremendous prospects for industrial applications for the synthesis of MIBK from acetone. This article reports a convenient access to MIBK from acetone through condensation and reduction procedures. Compared with conventional procedures, the method employed isopropanol as an alternative reductant to the dangerous H2 to reduce mesityl oxide (MO) into MIBK. The by-product from the reductant isopropanol was acetone and could be reused as the starting material to produce MO. After conditional optimizations, the MO conversion rate was enhanced to 95.8%, while the selectivity of MIBK was 98.8%. The two steps of reaction could be performed in one-pot.

Key words: Acetone, mesityl oxide (MO), catalysis, reduction, methyl isobutyl ketone (MIBK)
