Reaction Steps

Under stirring 0.05 g of 4-methyl-benzene sulphonic acid and 20 ml of chloroform are added to a mixture of 4.5 g of glucose and 19 g of choral. The mixture is heated to reflux temperature and the formed water is separated by means of a Dean-Stark apparatus. The solvent is distilled off, then the mixture is kept at a temperature of 60° C. for 20 minutes. The separated material is filtered off.
