  There is provided a process for producing MMA characterized by comprising the steps of: introducing an α-hydroxyisobutyric acid amide (HAM) production solution 5 into a thermal decomposition reactor 6; decomposing and separating non-reacted acetone cyanohydrin (ACH) to produce a HAM aqueous solution 11; contacting the HAM aqueous solution with ion exchange resins 12 and 13; dehydrating-hydrating it at a dehydration-hydration reactor 17 to produce methacrylic acid and/or methacrylamide 18 to which methanol 21 is added, which is esterified at an esterification reactor 22 to produce methyl methacrylate (MMA); contacting the MMA product 23 with a hydrophobic organic solvent 25 to extract MMA; separating MMA 42 by distillation; using the solvent 25, from which MMA is separated, for the liquid-liquid extraction; recovering methanol and by-product ammonia contained in the raffinate solution 27; using the methanol 37 as the starting material for the esterification reaction; using, for the ACH synthesis, a mixture 10 of the acetone and the hydrocyanic acid discharged from the thermal decomposition reactor 6; and recycling the resultant ACH as a starting material for the hydration reaction. The present invention permits production of MMA of high purity, elongating the lifetime of the catalyst. In addition, the recovered product(s) may be recycled. The present invention is thus suitable for industrial production of MMA.

  提供了一种生产甲基丙烯酸甲酯（MMA）的方法，其特征在于包括以下步骤：将α-羟基异丁酸酰胺（HAM）生产溶液5引入热分解反应器6；分解和分离未反应的丙酮氰醇（ACH）以产生HAM水溶液11；将HAM水溶液与离子交换树脂12和13接触；在脱水-水合反应器17中进行脱水-水合处理，以产生甲基丙烯酸和/或甲基丙烯酰胺18，然后加入甲醇21，在酯化反应器22中酯化以产生甲基丙烯酸甲酯（MMA）；将MMA产物23与疏水性有机溶剂25接触以提取MMA；通过蒸馏分离MMA42；使用从中分离MMA的溶剂25进行液-液萃取；回收包含在残渣溶液27中的甲醇和副产物氨；将甲醇37用作酯化反应的起始原料；对于ACH合成，使用从热分解反应器6排放的丙酮和氢氰酸的混合物10；并将所得的ACH回收再利用作为水合反应的起始原料。本发明允许高纯度MMA的生产，延长催化剂的使用寿命。此外，回收的产物可以再循环利用。因此，本发明适用于MMA的工业生产。
