防老剂TMQ的总氮含量测定

Determination of Total Nitrogen Content of Antioxidant TMQ

介绍防老剂TMQ总氮含量的测试步骤和数据处理方法。结果表明:本总氮含量测试方法有效;普通防老剂TMQ的总氮含量控制在7.2%～7.6%之间比较合适,高有效成分含量防老剂TMQ的最佳总氮含量范围需结合胶料性能确定。

The test procedure and data processing method for the determination of the total nitrogen content of antioxidant TMQ were introduced. The experimental results demonstrated that the test method was effective. The total nitrogen content of ordinary antioxidant TMQ was controlled in the range of 7.2% to 7.6%. However, for antioxidant TMQ which had a high content of active ingredient, the best range of total nitrogen content had to be designed by considering the properties of the rubber compounds.
