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.

This review is the second part of the consideration of modern approaches to the synthesis of cellulose acetates and is devoted to cellulose acetylation under the basic catalysis conditions (in the presence of halide and acetate anions, organic superbases, amines, inorganic bases). Analysis of methods for cellulose acetates producing based on the esterification with acetic anhydride and the transesterification with acetic acid esters was carried out. Acetylations of cellulose in solutions (homogeneous acetylation) and in suspensions (heterogeneous acetylation) are considered. Based on the literature data, current trends in research on cellulose substrates acetylation and scientific background for the development of new manufacturing technologies are determined.
