| 摘 要： | 引言 甲基丙烯酸甲酯（MMA）是重要的有机化工原料．目前主要采用丙酮氰醇法（ACH法）生产，该法存在原料剧毒、使用高腐蚀性硫酸、原子利用率低等缺点．异丁烯（IB）氧化法以其原料广泛、过程无废物排放、原子利用率高等优点，被工公认为生产MMA的清洁工艺技术．

| Abstract: | Supported multi-metal catalyst was prepared by impregnation.A variety of factors such as reaction temperature, feedstock ratio, alkali concentration, catalyst concentration and antipolymerizer concentration were systematically investigated in terms of their effects on the oxidative esterification reaction for methyl methacrylate production from methacrolein.The experimental results showed that under the condition of temperature 333 K，methanol/methacrolein ratio 97∶1(molar ratio)，NaOH concentration 0.001 g•ml-1 and catalyst concentration 0.02 g•ml-1, methacrolein conversion and methyl methacrylate selectivity were about 100% and 71.4% respectively, after 30 min reaction. |
