Latest Patents

One of his latest patents is titled "Chlorination of sugars." This process involves the chlorination of sucrose or its derivatives through a reaction with thionyl chloride and a nitrogen base. The method utilizes a specific ratio of thionyl chloride and base for every free hydroxyl in a non-reactive moderately polar solvent. This innovative process is particularly suitable for the preparation of sucralose. Another patent, "Process for the chlorination of sugars," describes a method where sugars and partly protected sugar derivatives are chlorinated by reacting unprotected hydroxyl groups with thionyl chloride. This results in the formation of chlorosulphites, which are then displaced to insert chlorine atoms at various positions, all conducted in an inert solvent with the presence of a quaternary salt.
