摘要
介绍了凯氏定氮法在测定氯乙烯-丙烯腈共聚树脂中丙烯腈含量的应用及反应原理,对测试结果的准确性和重复性进行了研究,并与灼烧法进行了比较。实验结果表明:采用凯氏定氮法测定氯乙烯-丙烯腈共聚树脂中丙烯腈的含量是可行的,测定结果准确,重现性较好。
The application of kjeldahl nitrogen determination method to the measurement of acrylonitrile content in vinyl chloride- acrylonitrile copolymer was introduced as well as the reaction principle. The accuracy and repeatability of the measurement results were studied, and was compared with that of ignition method. The experiment results showed that the application of kjeldahl nitrogen determination method to the measurement of acrylonitrile content in vinyl chloride - acrylonitrile copolymer was feasible,and the measurement results were accurate with good repeatability.
