Popis:	The influence of water on the selective gas phase oxidation of acrolein to acrylic acid on Mo/V/W-mixed oxides was investigated by means of temperature-programmed experiments. In the presence of water, the rate of the acrylic acid formation is significantly pronounced. Selectivity- and yield-maxima are broadened and shifted towards lower temperatures. Nonetheless, the combustion remains unaffected. Furthermore, the catalysts stability remains likewise unaffected within the range of the experiments.
