La Doped

In this present work, rare earth elements La was added to catalysts for the oxidative esterification of methacrolein (MAL) to methyl methacrylate(MMA). Catalysts were characterized by means of BET techniques. Effects of La proportion, material liquid pH and catalyst amount on catalytic performance were investigated. The results indicated that the addation of La in appropriate proportion could improve the catalyst’s activity. 1.0% was found to be the optimum La additional amount. Under the condition of reation temperature 323K, w%(catalyst) 3.6%, proportion of La in the catalyst 1%, pH of material liquid 10.0 the MMA yield could reached up to 89.8%.
