In a distillation flask of polytetrafluoroethylene, a solution of 10 g of glucose in 100 g of hydrogen fluoride, prepared analogously to Example 1, was distilled under reduced pressure at an internal temperature of -30° C. The pressure was regulated between 100 and 130 mbar in such a way that steady distillation took place. After 2.5 hours, the residual HF content in the bottoms from the distillation was then only 5 g. The distillation was terminated, and the residue worked up in accordance with Example 1. 9.5 g of glucosyl fluoride were obtained.
