针对中国石油大学（华东）化学综合实验拟开设的“石油产品酸性含氧化合物测定”的实验项目，进行教学改革。选取克拉玛依加氢蜡油为原料，改进深色石油产品酸值测定法，筛选酸值测定所需的溶剂，研究表明：改进深色油品酸值测定法较好的溶剂为甲苯-异丙醇，溶剂比甲苯：异丙醇（V/V）为1：2，溶剂量为60 mL。选取汽油1、汽油2、汽油3、柴油为原料，改进浅色油品酸度测定法，省略中和95%无水乙醇步骤，加做空白。实验证明，无论是测定深色油品还是浅色油品的酸值，改进后的方法可行、简便，减少污染。

The acidity of the slurry-bed hydrocracking vacuum gas oil (VGO) of Karamay atmospheric residue (KLAR) was determined in different solvents to investigate the effect of solvents on determination of acid number in dark-colored oil. The experiment results show that, during determining acid number of dark-colored oil, the better solvent is toluene and isopropanol, the ratio of solvents is 1:2, solvent volume is 60 ml. The acid number determination method of light-colored oil was also improved in this paper. The improved method is simple and feasible.
