以多孔钛片为支撑体 ,将组成为HxCu1.2 PAs0 .6 Mo12 Oy 的杂多化合物与具有氧溢流效应的氧化物Sb2 O4 制成复合催化膜 ,在特制的膜催化器中进行异丁烯选择氧化反应。结果表明 ,杂多化合物—Sb2 O4 复合催化膜具有较高的催化活性 ,在适宜的条件下 ,甲基丙烯酸收率可达 2 6.3 % ,甲基丙烯醛收率可达 2 2 .4%。
The porous titanium sheet as a support, the composition of HxCu1.2 PAs0. Mo12 Oy heteropoly compounds and oxygen overflow effect of oxide Sb2 O4 composite catalyst film made in a special membrane catalyst for isobutylene selection Oxidation reaction. The results show that the heteropoly compound-Sb 2 O 4 composite catalyst has high catalytic activity. The yield of methacrylic acid is up to 23.3% and the yield of methacrolein is up to 22.4% under the proper conditions.
