Abstract

Addition of AlPO₄ during the preparation of VOHPO₄·0.5H₂O leads to a catalyst, following activation, comprising (VO)₂P₂O₇ and AlPO₄ that displays over twice the activity of the AlPO₄-free (VO)₂P₂O₇ for the oxidation of butane to maleic anhydride without loss of selectivity. This improvement is shown to occur, at least in part, as a consequence of an electronic promotion effect.
