Self-Condensation of Acetone on Strontium Stannate under Suprcritical Conditions
Aldol condensation of acetone on strontium stannate isstudied at a temperature of 250- 400 °C and a pressure of 2.5 and 12.5 MPa. The main reaction products are mesityl oxide and isophorone. It is shown that the SrSnO3 catalyst is stable under supercritical conditions and its productivity with respect to mesityl oxide isomers at 350 °C and 12.5 MPa equals 9 g • h-1 gcat-1, which is higher than in the gas phase.
