Abstract:
The acid properties of phosphomolybdic heteropolyacid of the 12th series, applied on SiO2, TiO2, and Al2O3 carriers and its sodium and copper salts, applied on SiO2, were investigated by the method of IR spectroscopy according to the adsorption of pyridine. The presence of Bronsted and Lewis acid centers was established in all the investigated catalysts. It was shown that the concentration and in a number of cases the strength of Bronsted acid centers can be varied by varying the degree of substitution of protons in the heteropolyacid by metal cations, the content of heteropolycompounds on the carrier, the degree of their dehydration, and the type of carrier used. This work is pertinent to the use of molybdenum catalysts in various partial oxidation processes.
