Abstract: Preparation of chlorinating reagent or chlorination reaction itself for use in a reaction such as production of high intensity sweetener trichlorogalactosucrose (TGS) from partially protected sucrose, comprising reaction of dimethylformamide (DMF) with thionyl chloride or another sulphur containing inorganic acid chlorides including sulphuryl chloride is faced with a problem of prolific release of gaseous by-products, that at times may lead to violent explosion also. This problem is solved by innovative addition of solid powder inert to the constituents of the chlorination reaction mixture to the reaction, or by adding DMF to acid chloride solution in that order. The invention also leads to use of isolated solid Vilsmeier reagent being used for chlorination in a solvent other than DMF making it possible to avoid altogether problems arising from use of DMF which include irrecoverable loss in alkaline as well as acid conditions, interference in crystallization of TGS and the like.

Abstract: 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.
