Abstract:

The methylation of galactomannans in organic media produced patterns of substitution which did not depend on the relative reactivity of the hydroxyls, but that were governed by the state of aggregation of the polysaccharides. Similar results were observed on acetylation of these polymers dispersed in formamide, as shown by study of the products of oxidation of the acetylated derivatives with chromium trioxide and the analysis of an acetylated galactomannan-like oligosaccharide. © 1986.
