RE elements La, Ce and Pr were added to catalysts for the oxidative esterification of methacrolein (MAL) to methyl methacrylate(MMA). Effects of RE elements proportion,pH,water content of material liquid and kinds of RE elements on catalytic performance of catalysts were investigated. The results indicated that the addation of La, Ce and Pr in appropriate proportion could improve the catalyst's activity. Addition of Pr was better than addition of La and Ce. Under the condition of reation temperature was 50℃,w%(catalyst) was 3.6% .proportion of Pr in the catalyst was 1% ,pH of material liquid was 10.5,water conten of material liquid was 0% the yield of MMA reached up to 90.4%. |
