| Abstract: | Effects of calcination temperature of catalyst and reaction conditions on catalytic performances of ZrO2/MnOx/ZnO catalyst in synthesis of methyl isopropyl ketone and diethyl ketone from methylethyl ketone and methnol had been studied. The suitable calcination temperature about 673 K. The optimum reaction conditions were:reaction temperature was about 643 K,LHSV 1.0-1.5 h-1, pressure 0.6-1.0 MPa and n (methanol)/n (methyl ethyl ketone)/n (water) =1/1/1. Under suitable conditions, methyl ethyl ketone conversion was up to 44.4%. Selectivities of methyl isopropyl ketone and diethyl ketone were 41.7% and 35.7% , respectively. |
