摘要：
The decomposition of 2-propanol has been chosen as a test reaction to study the acid-base character of ALPO-5 molecular sieves modified by nickel and molybdenum. It was found that the type of the active components as well as the mode of their introduction affect acid-base properties of catalysts. Arguments for formation of heteropolymolybdate structures on the molecular sieve surface have been adduced. The role of different fragments in the structure of the modified molecular sieves has been discussed in connection with acidity and basicity of the catalysts.
