METHOD FOR CONVERTING LEVOGLUCOSENONE INTO 4-HYDROXYMETHYL BUTYROLACTONE AND 4-HYDROXYMETHYL BUTENOLIDE WITHOUT USING ANY ORGANIC SOLVENT AND CATALYST
PROCÉDÉ DE TRANSFORMATION DE LA LEVOGLUCOSENONE EN 4-HYDROXYMETHYL BUTYROLACTONE ET 4-HYDROXYMETHYL BUTENOLIDE EN ABSENCE DE SOLVANT ORGANIQUE ET DE CATALYSEUR
Abstract
The invention relates to a method for converting levoglucosenone into 4-hydroxymethyl butyrolactone and 4-hydroxymethyl butenolide without using any solvent or catalyst, wherein the oxidation and hydrolysis of the levoglucosenone or hydrogenated levoglucosenone are carried out in a single step using an aqueous solution of H2O2.
