Abstract: Aiming at the synthesis methods of methylal，this paper reviews advances of acetalization，direct oxidation of methanol，and oxidation of dimethy ether，with respect to the types of catalysts. The existing problems are commented，such as low feed conversion，low product purity，etc. Development of synthesis methods should aim at simplification of process，environmentally friendly catalysts，improving conversion and product purity. On the other hand，the research progress of the kinetics of synthesizing methylal is summarized. The kinetics research is getting closer to the actual situation of industrial production from establishing models to choice of device，which is more valuable for industrial production.

摘要： 针对甲缩醛的合成方法，一方面以催化剂类型为主线，对醇醛缩合法、甲醇直接氧化法、二甲醚氧化法等进行了综述，并指出目前方法中存在的问题，如原料转化率低、产物纯度不高、催化剂稳定性差、工艺复杂等，进而指明甲缩醛合成应向着简化工艺、采用环保型催化剂、提高转化率和产品纯度的方向发展；另一方面，综述了国内外在甲缩醛合成反应动力学研究方向的进展情况，指出甲缩醛合成反应动力学的研究从模型的建立到装置的选择上都越来越接近工业生产的实际情况，对于工业化生产更具参考价值。甲缩醛合成动力学研究正在向着更加趋近于工业化生产的方向发展，可以为甲缩醛生产工艺和装置的建立提供更加有效的参考。
