Abstract : Batch-type microreactors (about 1/40 milliliter of reactants) were used to measure furfural yields from acidified xylose solutions containing sodium xylene-sulfonate. Initial xylose concentration was 0.666 molar. Two levels of sulfuric acid catalyst were used, 0.05 and 0.2 molar, while the sodium xylenesulfonate concentration ranged from 0 to 1.68 molar (close to saturation at room temperature). The reaction temperatures were 150, 200 and 240 C. It was found that presence of the salt did not affect the quantity of furfural produced, but greatly increased the rate of formation. The regular increase in rate of furfural formation was directly related to the increase in the rate xylose decomposition, and furfural yields for all salt and acid concentrations at a given temperature were uniquely described by the xylose half-life.
