A process for preparing specific cationic surface active agents in which nitrogen atoms are attached to both ends of a long-chain alkylene group or polyoxyalkylene group having at least 6-24 carbon atoms in the molecule, at least one of said nitrogen atoms constituting a quaternary ammonium structure, and also at least one hydroxyphenethyl group is bonded to at least one of the two nitrogen atoms. These cationic surface active agents can serve as an accelerator which catalytically promotes changes in a chemical and/or physical change process involving a hydrolyzing, deacidizing or extracting operation using an aqueous solution of an alkaline metal hydroxide or an alkaline earth metal hydroxide.
一种制备特定阳离子表面活性剂的工艺,其中氮原子连接到分子中至少有 6-24 个碳原子的长链烷基或聚氧亚烷基的两端,所述氮原子中至少有一个构成季铵结构,并且至少有一个羟基苯乙基键合到两个氮原子中的至少一个上。这些阳离子表面活性剂可以作为一种促进剂,在涉及使用碱金属氢氧化物或碱土金属氢氧化物水溶液进行水解、脱酸或萃取操作的化学和/或物理变化过程中催化促进变化。
