Abstract
In this paper we studied the synthesis of 2 methyl 2 pentenal from self aldol condensation of propionaldhyde, with anion exchange resin as the catalyst of the condensation.The optimum conditions were established: reaction temperature is 30?℃, reaction time is 2?h ,the dose of benzene as the solvent is 5?mL, anion exchange resin: CH 3CH 2CHO= 10?mmol/20?mmol, and 2 methyl 2 pentenal can be obtained with 93.54%? yield.
