摘要：
A process for the chlorination of sucrose or a derivative thereof, comprises reaction of the sucrose or derivative thereof with thionyl chloride and a nitrogen base at a ratio of about 1 molar equivalent (ME) of thionyl chloride and about 1 ME of base for every ME of free hydroxyl, in a non-reactive moderately polar solvent. The process is particularly suitable for the preparation of sucralose.
