石油产品酸值测定方法比较及影响因素探讨

摘要

介绍国内外石油产品酸值测定的标准方法及其各自的特点和差别，并采用常用的3种分析方法对多种石油产品进行分析比较。确定适合原油酸值测定的方法为电位滴定法，探讨了影响酸值准确性的几种主要因素，提出了与原油酸值测定相适应的分析条件。%This paper introduced the domestic and foreign standard test methods of acid value of petroleum products, including their respective characteristics and differences. Three commonly used methods were taken to analyze various petroleum products. Potentiometric titration method was selected. Several major factors influencing the accuracy of the method were studied, and appropriate test conditions for acid value were put foward.
