Показано, что реакция эффективно протекает в присутствии морденита в качестве катализатора, который подавали в виде суспензии в глицерин-метанольном растворе (глицерин : метанол = 2 : 1 об./об.), при мольном отношении ацетон : глицерин, равном 1,5. Определены основные факторы (длина микрореактора, скорость подачи реагентов и температура реакции), влияющие на скорость реакции и на селективность по золькеталю. Максимальная конверсия глицерина (64,8 %) и селективность по золькеталю (94,3 %) были получены при 40 °С, времени контакта 18,85 мин в микрореакторе длиной 3 м и внутренним диаметром канала 2 мм. Показана эффективность применения микрореактора по сравнению с реактором периодического действия (РПД). Удельная производительность по золькеталю в микрореакторе была в 14 раз выше по сравнению с РПД. Полученные результаты показывают, что применение микроканальной технологии можно рассматривать как перспективный вариант для интенсификации реакции получения кеталей и ацеталей глицерина.</p></abstract><trans-abstract xml:lang="en"><p>The possibility of using a microchannel (MC) reactor for the synthesis of solketal from glycerol and acetone is demonstrated. The reaction proceeds efficiently in the presence of mordenite as a catalyst, which was fed as a suspension in a glycerol-methanol solution (glycerol/methanol = 2:1 v/v) at an acetone/glycerol molar ratio of 1.5. The main factors (MC reactor length, reactant feed rate, and reaction temperature) influencing the reaction rate and solketal selectivity were determined. The maximum glycerol conversion (64.8%) and solketal selectivity (94.3%) were obtained at 40 °C, a residence time of 18.85 min in a 3 m long MC reactor with a channel inner diameter of 2 mm. The efficiency of using the MC reactor in comparison with a batch reactor is demonstrated. The specific productivity of solketal in the MK reactor was 14 times higher than that of the batch reactor. These results indicate that microchannel technology can be considered a promising option for intensifying reactions for producing glycerol ketals and acetals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микрореактор</kwd><kwd>золькеталь</kwd><kwd>глицерин</kwd><kwd>ацетон</kwd><kwd>морденит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microchannel reactor</kwd><kwd>solketal</kwd><kwd>glycerin</kwd><kwd>acetone</kwd><kwd>mordenite</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Министерства науки и высшего образования РФ в рамках государственного задания Института катализа СО РАН (проект FWUR-2024-0035).
