Sažetak
Acidic properties and the catalytic activity of 12-molybdophosphates
(M"nn+H3-,PM012040; M = Cu2+, BP+, Cr3+ and X = 1-3) have been studied. The results are discussed as the effect of these catalyst components on the partial charge on oxygen atom which is in a relation with the acidity. It is shown that the oxygen-hydrogen bond is weakened as the value of partial charge on oxygen (-bo) becomes more negative, while the vapor-phase dehydration activity of 2 propanol is explained on the basis of the reacting zone wideness taking into account the pseudo liquid phase nature of the heteropoly compounds. Correlation, the percentage conversion of 2-propanol with the fractional charge on molybdenum atom was successful to interpret the effect of the redox properties of these catalysts on their catalytic activity.
