Abstract The process of dehydration condensation of acetone was simulated with Aspen Plus. We conducted a series of experiments to obtain the reaction kinetics of acetone dehydration condensation for diacetone alcohol (DAA) and mesityl oxide (MSO). The effect of reaction temperature on reaction ratio was discussed. As a result, a reaction kinetic model was established. A user-supplied subroutine was compiled to the Aspen Plus. During the simulation process, the influences of the number of reaction sections, the feed stage, the number of rectification sections and the number of stripping sections were discussed. Under the optimized process conditions of the reactive distillation column, the conversion of acetone reaches to 99%, and the selectivity of MSO is up to 93%.
