建立了用间二硝基苯快速检测己内酰胺的方法,采用含有2%间二硝基苯的乙醇溶液与己内酰胺在氢氧化钾存在下的显色反应进行。实验结果表明,该方法简便、快速,成本低,适合己内酰胺的现场快速定性测定。
A rapid method for the determination of caprolactam with m-dinitrobenzene has been developed using a chromogenic reaction of 2% m-dinitrobenzene in ethanol with caprolactam in the presence of potassium hydroxide. The experimental results show that the method is simple, rapid, low cost and suitable for rapid qualitative determination of caprolactam in the field.
