Abstract

В заявке описан способ кислотно-катализируемой деполимеризации целлюлозы, заключающийся в том, что целлюлозу подвергают в присутствии неорганической кислоты и/или органической кислоты механической обработке. При этом достигается практически полное каталитическое превращение целлюлозы в водорастворимые продукты, в качестве которых получают олигомеры целлюлозы, целлобиозу, глюкозу и глицерин без образования других побочных продуктов в сколько-нибудь значительных количествах.
