Conclusions
-
1.
The kinetics was studied for the condensation of acetone under the action of 50% aq. NaOH. The introduction of phase-transfer catalyst Q+Cl− leads to a significant decrease in the reaction rate.
-
2.
A scheme was proposed for the aldol condensation with or without phase-transfer catalyst. The decrease in the reaction rate is explained by blockage of the heterogeneous pathway due to anion exchange.
