Синтез ацетатов целлюлозы. Часть II. Ацетилирование целлюлозы в условиях основного катализа

Данный обзор является второй частью рассмотрения современных подходов к синтезу ацетатов целлюлозы и посвящен методам ацетилирования целлюлозы в условиях основного катализа (в присутствии галогенид- и ацетат-анионов, органических супероснований, аминов, неорганических оснований). Проведен анализ способов получения ацетатов целлюлоз, основанных на реакциях этерификации уксусным ангидридом и переэтерификации эфирами уксусной кислоты. Рассмотрены методы ацетилирования целлюлозы в растворах (гомогенное ацетилирование) и в суспензиях (гетерогенное ацетилирование). На основе литературных данных определены современные тенденции в исследованиях ацетилирования целлюлозных субстратов и научные предпосылки для разработки новых промышленных технологий.
