    • 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.
    • 制备氯化试剂或氯化反应本身用于反应,例如从部分保护的蔗糖生产高强度甜味剂三氯半乳蔗糖(TGS),包括二甲基甲酰胺(DMF)与亚硫酰氯或另一种含硫的无机酰氯(包括磺酰氯)的反应 存在气态副产物多产释放的问题,有时也可能导致剧烈的爆炸。 通过将氯化反应混合物的成分惰性的固体粉末添加到反应中,或者通过向该酰氯溶液中依次加入DMF来解决这个问题。 本发明还导致使用分离的固体维尔斯迈尔试剂用于在DMF以外的溶剂中进行氯化,使得可以避免使用DMF引起的一切问题,其包括在碱性和酸性条件下不可恢复的损失,TGS的结晶干扰 等等。
