摘要：

Solid-state hydrolysis proceeded with cellulose and methyl alpha- and beta-D-glucopyrano sides in the presence of hydrated magnesium chloride. This reaction was effective even at > 100 degrees C since the hydrated water, which is held by MgCl2 UP to > 200 degrees C, is utilized as a nucleophile. Excess water made this reaction ineffective due to the competition between water and sugar oxygen atoms in coordinating with Mg2+, a Lewis acid. Consequently, this hydrolysis reaction is characteristic of solid-state reactions. (c) 2007 Elsevier Ltd. All rights reserved.
