| Abstract: | The catalytic behaviour of oxidative dehydrogenation of isobutyl acid to methylacrylic acid on the V-substituted molybdenum heteropoly compounds was studied. The effect of vanadium on the stability and acidic property of the catalyst was also investigated by means of IR and DTA, The ESR results show that the vanadium not only changed physical-chemical properties of the catalyst, but also participated in the reaction, becoming a new catalytic site. |
