摘要: 以丙烯羰基合成制丁辛醇装置副产物异丁醛为原料制甲基丙烯酸(MAA)是有机玻璃单体生产的最经济的工艺路线。我们在异丁酸氧化脱氢制甲基丙烯酸杂多酸催化剂研究的基础上,为了进一步提高甲基丙烯酸的收率和解决异丁酸与甲基丙烯酸分离上的困难,开展了异丁醛一步氧化脱氢制MAA的研究工作。其结果与两步法比较,MAA总收率提高了10%以上。

Abstract: In this paper, it is reported that iso-butyralaldehyde (IBA) is directly oxided to methacrylic acid (MAA) by P, Mo, Vheteroacid salt containing rare earth. In space velocity 1500 hr-1 and IBA: O2:H2O:N2 = 1:2.5,: 7:10 (mole ratio) conditions, yield of MAAis 63% and yield of methacrolein is 15% in single way, total yield of MAAexceeds 70%. Comparing with two step method of iso-butyralaldehyde oxidation, yield of MAAis raised over 10% and difficulty of separating iso-butyric acid and MAAcan be avoided. The method is the most economical route.
