  • Use of Acid Scavengers in Removal of Protons (Acidity) of the Reaction Mass During Chlorination of Sucrose-6-Acetate
    Publication number: 20090163704
    Abstract: A process is described wherein efficiency of chlorination is improved in a process for production of a chlorinated sucrose by scavenging, using an acid scavenger, of excess of acidic protons formed during a chlorination reaction between 6-O-acyl sucrose in dimethylformamide and a chlorinating reagent.
    Type: Application

  • Generation of Phosphorus Oxychloride as by-Product from Phosphorus Pentachloride and DMF and its Use for Chlorination Reaction by Converting Into Vilsmeier-Haack Reagent
    Publication number: 20090131653
    Abstract: A process is described wherein after formation of first crop of Vilsmeier-Haack reagent by reacting Phosphorus Pentachloride with N,N-dimethylformamide to form a first crop of Vilsmeier reagent as insoluble crystals, a by-product of this reaction, the Phosphorus Oxy-Chloride, reacts with N,N-dimethylformamide to give a second crop of Vilsmeier reagent. This second crop of Vilsmeier reagent is soluble in DMF. This process makes it possible to double the yield of chlorinated substrate, such as sucrose-6-acetate or sucrose-6-benzoate, from the same quantity of Phosphorus Pentachloride.
