| Abstract | Methacrolein (MAL) is an important chemical for the manufacture of methyl methacrylate and a key monomer in many polymerization reactions. In this study,l-proline was investigated as the catalyst for the aldol condensation of formaldehyde and propionaldehyde to produce MAL. The catalytic activity of the reaction system was closely related to the competition between the main reaction synthesizing MAL and the side reaction producing 2-methyl-2-pentenal, which could be modified by adjusting the operating parameters. The influences of several operating conditions, including temperature, reaction time and water content, on the catalytic performance of the system were systematically studiedviaa series of single-factor experiments, and the optimized reaction conditions were obtained. The mechanistic investigationviaESI-MS indicated that the reaction pathway followed the Mannich route. Experimental and theoretical kinetic analyses of thel-proline-catalyzed aldol condensation reaction were performed, and the reaction orders of the reactants were obtained by regression. The results showed thatl-proline was an efficient catalyst for the production of MALviaaldol condensation under mild conditions. |
