Abstract
H 3PMo 12O 40 embedded in a polysulfone film was prepared by blending H 3PMo 12O 40 with polysulfone using dimethylformamide as a common solvent and its catalytic activity for 2-propanol conversion reaction was examined. The prepared film catalyst showed a higher yield for acetone but a lower yield for propylene than H 3PMo 12O 40 itself. The decrease of acidic function of the film catalyst was mainly due to dimethylformamide strongly adsorbed on the acid sites of H 3PMo 12O 40, while the increase of oxidation function was due to uniformly and finely distributed H 3PMo 12O 40 in the film. When the film catalyst was used as a membrane, it showed higher ratio of acetone to propylene than H 3PMo 12O 40 itself.
