| 摘 要： | 为了能够准确测定深色油品中的碱性氮含量，对石油产品中碱性氮的测定方法进行了阐述和对比。在此基础上进行了新方法的探究，用电位滴定法测定汽油、柴油、渣油油品中碱性氮含量。通过以手动滴定为基础，用电位滴定法测定了几种深色油品的碱性氮含量，结果显示试验数据准确，重复性良好，满足SH／T0162中的误差范围的要求，可以作为SH／T0162之外的另一种可供选择的分析方法。

| Abstract: | In order to accurately determine the basic nitrogen content of dark oils, the determination methods for basic nitrogen in petroleum products were elaborated and compared in this paper. A potentiometric titration method was explored to determinate the basic nitrogen content of gasoline, diesel and residual. Based on the manual titra？tion, the basic nitrogen content of dark oils was determined by using potentiometric titration method. The experi？mental data is accurate, with good reproducibility. The error is within the range of the SH/T0162. It can be an al？ternative method besides the analysis criterion SH/T0162. |
