Vorschrift

254.7 g (1.6 mol) of sulfur trioxide pyridine were slurried in 1300 ml of water-free pyridine. With stirring, 68.5 g (0.2 mol) of sucrose were added. The reaction mixture was heated to 65° C. and kept at this temperature for 240 minutes. As the reaction proceeded, the substance was separated as a thick flowing oil. When the reaction was terminated, the agitator was stopped, the pyridine phase was decanted, and the oily phase was dissolved in 600 ml of ion-exchanged water.
