Reaktionsschritte

A reaction vessel containing 5 g NaOH and 0.2 g sodium anthraquinone-2-sulphonate, AMS, Merck Co., in 150 ml of a solution of 80 mass-% of methanol in water, was kept at a temperature of 25° C. L-sorbose, Merck Co., (70 g/130 ml water) and NaOH (32 g/32 ml water) was added batchwise with 15 min intervals while mixing. Oxygen was added to the mixture and the reaction was continued for about 2 h. The major end product was L-xylonic acid, in addition, treonic acid, glyceric acid and glycolic acid were formed, as well as a large amount of formic acid.
