摘要： The present invention provides a method for synthesizing cationic bleach activators via a single-bath reaction, comprising steps of: separately dissolving 4-chloromethylbenoyl chloride and lactam in its respective solvent, adding an acid-binding agent to the lactam solution, next adding dropwisely 4-chloromethylbenoyl chloride solution into the lactam/acid binding-agent solution, and finally adding tertiary amine to the solution above to make a reaction solution, which is further treated with mixing and refluxing. The washed and dried final product is TBLC cationic bleach activator. The method of the present invention greatly simplifies the synthesizing process and lowers the stringency of reaction conditions for preparing cationic bleach activators (TBLC). At the same time, the present method produces TBLC cationic bleach activators with high yields, making it a suitable option for industrial production of these bleach activators.

摘要翻译： 本发明提供了通过单浴反应合成阳离子漂白活化剂的方法，包括以下步骤：将4-氯甲基苯甲酰氯和内酰胺分别溶解在其各自的溶剂中，向内酰胺溶液中加入酸结合剂，然后逐滴加入4 - 氯甲基苯甲酰氯溶液加入到内酰胺/酸结合剂溶液中，最后向上述溶液中加入叔胺制成反应溶液，进一步用混合和回流处理。 洗涤和干燥的最终产品是TBLC阳离子漂白活化剂。 本发明的方法大大简化了合成过程，降低了制备阳离子漂白活化剂（TBLC）的反应条件的严格性。 同时，本方法生产具有高产率的TBLC阳离子漂白活化剂，使其成为这些漂白活化剂的工业生产的合适选择。
