Abstract
The influence of the composition and structure of heteropolyacids (HPA) on their catalytic activity in the liquid phase synthesis of methyl tert-butyl ether (MTBE) at 42 °C has been studied. The activity of HPA is compared with that of other acid catalysts. The most active are HPA's of the Dawson structure, then come HPA's of the Keggin and Dexter-Silverton structures. HPA salts have low activity in the synthesis of MTBE.
Abstract
Изучено влияние состава и структуры гетероликислот (ГПК) на их каталитическую активностй в жидкофазном синтезе метилтретбутилового эфира (МТБЭ) при 42°C. Активность ГПК сравнивалась с активностью других кислотных катализаторов. В ряду ГПК наиболее активными были ГПК стрыктуры Доусона, затем ГПК структувы Кеггина и Декстера-Сильвертона. Соли ГПК малоактивны в синтезе МТБЭ.
