摘要: 首次考察了Dawson结构的钨磷酸对乙苯氧化脱氢制苯乙烯的催化行为,并与Keggin结构的钨磷酸进行了对比。结果表明,较短的增活期可能与表面积碳物具有更多的未成对电子有关。

关键词: Dawson结构的钨磷酸, 苯乙烯, 乙苯氧化脱氢

Abstract: We have first studied the catalytic behaviour of H6P2W18O62 and compared with H2PW12O40 in the oxidative dehydrogenation of ethylbenzene to styrene. The interesting results were obtained. The shorter increasing time of activity can be related to the more unpair electrons of carbonaceous material on the surface.

Key words: Dawson H6P2W8O62, Styrene, Oxidative dehydrogenation of ethylbenzene
