Abstract

In the process of the aldol condensation of acetone the preparation of mesityl oxide has been studied with respect to the temperature and the nature of catalyst. Strong basic ion exchangers Ionenaustauscher III (Merck III) and Lewatit MP 500 were used in the temperature range from 0 to 50°C. Better results are achieved with Merck III, as is evident from DAA/MO yields, rate constants and energy activation values. Empirical expressions for DAA/MO production are given.

Abstract

Исследовали влияние температуры и природы катализатора на процесс альдольной конденсации ацетона при получении окиси мезитила (ОМ). Использовали сильные основные ионообменники марки Ionenaustauscher III (Merck III) и Lewatit MP 500 в интервале температур от 0 до 50°C. Исходя из выходов ДАС/ОМ (ДАС=диацетоновый спирт), величин констант скоростей и знергий активации, лучшие результаты достигнуты при использовании Merck III. Приводятся эмпирические выражения производ-ства ДАС/ОМ.
