橡胶中油酸含量测定

Determination of Oleic Acid Content on Rubber

油酸作为中止剂(终止催化剂活性)以及降粘剂,对橡胶组成稳定性(变色)以及回弹性(高尔夫球)有重要影响。目前尚无橡胶中油酸含量标准分析方法,为此建立了液相色谱测定橡胶中油酸含量的分析方法。研究发现,该方法的检出限为0.003mg/mL、定量限为0.03mg/mL、回收率为100.7%~117%,检测发现目前某橡胶厂产品油酸含量在0.35%左右。实验证明,该方法可用于装置生产过程中的质量监控以及工艺参数优化调整。

Oleic Acid,as a discontinuing agent(termination of catalyst activity) and a viscosity reducing agent,has an important effect on composition stability(discoloration) and resilience( golf ball) of Rubber. The detection limit of the method was 0.003 mg/mL,the quantitative limit was 0.03 mg/mL,and the recorery was 100%-117%. The content of Rubber is about 0.35%. The experiment shows that the method can be used for quality control and process parameter optimization.
