Abstract
The heterogeneous reactions of fatty acid ketene dimer with methyl α-D-glucopyranoside, maltose, cellobiose, microcrystalline cellulose and a bleached kraft pulp have been investigated under base catalyzed conditions in N,N-dimethylformamide (DMF). The reaction products have been examined by 13C-NMR and/or infrared spectroscopy. The spectral data provide the first direct evidence for β-ketoester formation with these substrates.
