摘要：
One-step synthesis of methylmethacry late (MMA) using heteropoly compounds (HPCs) as catalysts was demonstrated by feeding a mixture of methacrolein (MAL), air, water, nitrogen and MeOH (methanol). The HPCs with different counter-ions, such as H1.7Cs1.5Cu0.25As0.1PMo11VO40 (CsPMo11VO40), H(1.7)La(0.7)Cu(0.2)5As(0.1)PMo(11)VO(40)(LaPMo11VO40) and H1.7K1.5Cu0.25As0.1PMo11VO40 (KPMo11VO40), were studied in oxidation of MAL, esterification of methacrylic acid (MAA) and one-step synthesis of MMA from MAL, respectively. The selectivity of MAA was up to 45.7% and MMA was 44.6% with 93.3% MAL conversion over CsPMo11VO40.
