||PCT/IN2006/000327||PHARMED MEDICARE PVT. LTD. ||RATNAM, Rakesh |
This invention relates to a process for selective capture, isolation and purification of chlorinated sucrose compounds, including chlorinated sucrose, their precursors and derivatives, including trichlorogalactosucrose (TGS), directly from chlorinated reaction mixture by column chromatography on adsorbents and under conditions which result in specific and selective affinity towards one or more of chlorinated sucrose compound. The process also integrates de-esterification of chlorinated sucrose esters adsorbed on the adsorbent while they are being treated with desorbent. The process also provides a novel approach to concentration and crystallization of TGS. The chlorinated sucrose derivatives, including TGS, thus isolated are substantially free from most impurities, salts and organic solvents. The process has high recovery of more than 95% in terms of desired chlorinated sucrose derivatives including TGS.

||PCT/IN2006/000151||PHARMED MEDICARE PRIVATE LIMITED ||RATNAM, Rakesh |
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 DIV1F. 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.
