十二烷胺又名月桂胺,它是一种表面活性剂。我们曾用它作工业氯化铵防结块试验,效果较好。由于加入添加剂数量很少,在成品工业氯化铵中十二烷胺的含量就很低,在大量铵盐存在下分析微量的十二烷胺,目前国内还未见报导,据了解,国内有些同类型厂在没有合适分析方法的情况下,用测溶液表面张力的方法来确定微量十二烷胺的含量,据认为结果不够理想。为此我们进行了多种方法试验,认为如下方法还是可用的,操作简单方便,色阶明 Dodecylamine, also known as lauryl amine, is a surfactant. We have used it as industrial ammonium chloride anti-caking test, the effect is better. Due to the small amount of additives added, the content of dodecylamine in finished industrial ammonium chloride is very low. It is still not reported in our country to analyze trace amounts of dodecylamine in the presence of a large amount of ammonium salts. It is understood that some domestic The same type of plant in the absence of a suitable analytical method, the method of measuring the surface tension of the solution to determine the trace amount of dodecylamine, the results are considered less than ideal. To this end we conducted a variety of test methods, that the following method is still available, easy to operate, the color level
