Abstract: In this paper, we reported the result of infrared study about methacrolein (MAL) adsorption on heteropoly acid catalyst, H4PMo11V1O40/SiO2.The three surface species CH2=C(CH3)-CHO(Ⅰ), CH2=C(CH3)-CO (Ⅱ) and(这里有图片198707-639-3.gif)(Ⅲ) were formed on the catalyst surface. We considerthat they are the intermediate compounds of methacrylic acid (MAA) to form. It was found that at 300℃ MAL chemisorption did not occur on the catalyst under the evacuating condition. VP-Oand VMe-O-Mebands, characterizing the heteropoly acid anion structure, disappeared.
