Abstract

In the series of Al2O3, MgO and Al2O3−MgO catalysts, those containing about 75% Al2O3 and 25% MgO show the highest activity in the decomposition of diacetone alcohol in non-polar solvents. The fastest rates of reaction, which follows the zero-order kinetics over the whole range of conversion, coincide with the occurrence of strong basic sites on the catalyst surface.

Abstract

В серии катализаторов Al2O3, MgO и Al2O3−MgO самую большую активность проявляют катализаторы, содержащие около 75% Al2O3 и 25% MgO, эти катализаторы разлагали диацетоновый спирт в неполярных растворителях. Самые большие скорости реакции кинетика которых подчиняется нулевому порядку, совпадаут с появлением на поверхности основных центоров.
