METHOD OF MANUFACTURING LACTULOSE ANHYDRIDE.

摘要

A method of manufacturing lactulose anhydride, comprising the step of drying lactulose trihydrate at a temperature of 45-75 DEG C and with a degree of vacuum of 25-100 Torr so as to remove water of crystallization therefrom. The method is capable of manufacturing lactulose anhydride by a simple step at a high yield and a low cost, and suitable for manufacturing lactulose anhydride in large quantities on an industrial scale.
