Abstract

PURPOSE: To obtain δ-gluconolactone useful as a food additive for confectionery leavening agents and paste products simply in high yield, by treating the crude oxidation product of glucose with an acid.
CONSTITUTION: Glucose (G) is oxidized with molecular oxygen in the presence of an organic solvent, e.g. diethyl ether acetonitrile, methanol, or dimethyl formamide, in an amount of 20W200 times that of G and a catalyst comprising palladium or platinum. The resulting reaction mixture or a crude product after distilling off the solvent is dissolved in a suitable solvent, and treated with an inorganic acid, e.g. hydrochloric acid, an organic acid, e.g. p-toluenesulfonic acid, or a strongly acidic ion exchange resin to form the objective compound.
