摘要: 甲基丙烯酸甲酯(MMA)是一种重要的有机化工原料,被广泛用于制备表面涂层、合成树脂、油漆涂料和高分子材料等。随着我国石化工业的不断发展,特别是大型乙烯装置的建成,将会副产大量的C4烃(异丁烷和异丁烯等),经C4烃氧化法生产MMA清洁工艺表现出明显的经济和技术优势。其中,C4烃氧化制备甲基丙烯醛(MAL)是C4烃生产MMA的关键步骤。综述了C4烃氧化制备MAL的催化剂(Mo-Bi系,Mo-Sb系,Mo-V-Te系,杂多酸系及V系等催化剂)的研究现状,并提出了未来催化剂的重点研究方向。

Abstract: Methyl methacrylate (MMA) is an important organic chemical raw material, which is widely used in the preparation of surface coatings, synthetic resins, paint coatings, and polymer materials. With the continuous development of China's petrochemical industry, especially the construction of large-scale ethylene plants, C4 resources (isobutane and isobutylene, etc) are becoming increasingly abundant, therefore, the clean process of producing MMA via C4 hydrocarbon oxidation shows significant economic and technological advantages. The oxidation of C4 hydrocarbons to methacrolein (MAL) is the key step of C4 hydrocarbon oxidation to produce MMA. The research status of catalysts (including Mo-Bi, Mo-Sb, Mo-V-Te, heteropoly acid and V-based catalysts) for the oxidation of C4 hydrocarbons to methacrolein was mainly reviewed, and the key research directions of catalysts in the future were further explored.
