十八烷基双聚氧乙烯基苄基氯化铵的合成方法
摘要：
本发明公开了一种十八烷基双聚氧乙烯基苄基氯化铵的合成方法，以十八烷基伯胺、环氧乙烷和氯化苄为原料，其特征在于包括以下步骤：A)聚合，聚合所需原料为十八烷基伯胺与环氧乙烷，生成聚氧乙烯十八烷基胺；B)季铵化反应，所述聚氧乙烯十八烷基胺与氯化苄以1∶0.5～1.1摩尔比，在极性介质中，70～100℃温度环境，回流下进行季铵化反应，反应4～12小时后，制得十八烷基双聚氧乙烯基苄基氯化铵。本发明方法制得的产品适用于各种酸性染料的染色，并可降低酸的用量，减少对纤维的损伤；用量多时可作为剥色剂使用。在水中的溶解性较好，溶解速度很快，且具有良好的增溶作用，对大多数酸性染料的增溶作用显著。
摘要（英）：

The invention discloses a method for synthesizing octadecyl bi-polyoxyethylene benzyl ammonium chloride. Octadecylamine, ethylene oxide and benzyl chloride are taken as raw materials; and the method is characterized by comprising the following steps of: A) polymerizing the octadecylamine and the ethylene oxide to obtain polyoxyethylene octadecylamine; and B) performing quaterisation reaction on the polyoxyethylene octadecylamine and the benzyl chloride in a molar ratio of 1:(0.5-1.1) at the temperature of between 70 and 100DEG C for 4 to 12 hours in a polar medium under the condition of refluxing to obtain the octadecyl bi-polyoxyethylene benzyl ammonium chloride. The product prepared by the method is suitable for dyeing of various acid dyes, the using amount of acid can be reduced, and the damage to fibers is reduced; and when the using amount is large, the product can be used as a stripping agent. The product has high solubility in water, high solution rate, good solubilization effect and obvious solubilization effect on most acid dyes.
