摘要：

Aldol condensation of acetone was studied over solid base CaO-SnO2 catalyst in the 300-450 Alpha degrees C temperature range and at 15-75 atm pressure in a fixed-bed reactor. The main products are mesityl oxide and isophorone. The high stability of CaO-SnO2 catalyst performance was observed at pressure of 75 atm giving the acetone conversion of 36-41%. Increase in the temperature and pressure led to a simultaneous raise in acetone conversion. The maximum conversion of 41% was achieved at 400 degrees C, 75 atm and a flow rate of acetone of 8.1 g h(-1) (g catalyst)(-1).
