title: Solid-state hydrolysis of cellulose and methyl alpha- and beta-D-glucopyranosides in presence of magnesium chloride.
abstract: Solid-state hydrolysis proceeded with cellulose and methyl alpha- and beta-D-glucopyranosides in the presence of hydrated magnesium chloride. This reaction was effective even at >100 degrees C since the hydrated water, which is held by MgCl(2) 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 Mg(2+), a Lewis acid. Consequently, this hydrolysis reaction is characteristic of solid-state reactions.
