Abstract

Работа посвящена исследованию закономерностей синтеза простых метиловых эфиров глицерина (МЭГ) в реакции прямой межмолекулярной дегидратации, протекающей между глицерином (ГЛ) и метанолом в присутствии цеолита типа BEA. Варьируемые условия реакции: температура (140, 160 и 180°С), давление (3.0, 5.0 и 7.0 МПа), объемная скорость подачи сырья (0.5 и 1.0 ч-1), мольное соотношение метанол : глицерин (5 : 1; 10 : 1). Описаны составы получаемых реакционных смесей, дана характеристика изомерного состава получаемых моно- и дизамещенных эфиров глицерина. Приведены материальные балансы реакции применительно для каждой комбинации рабочих параметров, показан характер изменения конверсии глицерина, выходов эфиров глицерина и побочного диметилового эфира (ДМЭ), а также селективности между моно- и дизамещенными эфирами глицерина в зависимости от условий реакции.
