| 摘 要： | 通常以酚欧和甲基但作为指示剂进行酸碱满足测定游离碱度．催化汽油碱渣中的酚类化合物对游商碱度的测定有正项干扰．这个干扰可以由碱度差减去酚的浓度来消除．试验表明，该方法比碱度差方法误差小。使用方法可获得可信的结果．

| Abstract: | The determination of free alkali is usually carried out by acid-base titration using phenolphthalein and methyl orange as the titration indicators. The phenols containing in the FCC gasoline caustic sludge often bore positive interference effect,and this can be overcome by the method of the alkalinity difference abstracting the phenol content in the sample. Practical experiments showed that the error of the abstraction method is lower than that of alkalinity difference method. By using the abstraction method, better results can be obtained. |
