以废内燃机油为原料,二乙烯三胺为脱酸剂,考察了反应时间、反应温度、搅拌速度及二乙烯三胺的用量对脱酸效果的影响。实验结果表明：随着反应时间延长和反应温度的升高,脱酸率先增大后减小;随着搅拌速度和剂油比的加强,脱酸率一直增大。结合正交实验得出的最佳工艺条件为反应时间3h、反应温度160℃、转速300r/min、剂油比（g：g）1：300,此时1#废机油的酸值可以从0.5195 mgKOH/g降到0.0293 mgKOH/g,脱酸率达94.36%。对不同的废内燃机油进行脱酸——白土精制,再生油的各项理化指标均得到很好的改善,基本接近HVI型润滑油基础油的质量标准。

We use waste internal combustion engine oil as material,diethylenetriamine as deacidification agent,to investigate the influence of the reaction time,reaction temperature,stirring speed,catalyst to oil ratio to the effect of deacidification.The results show that： when the reaction time is 3h,reaction temperature is 160 ℃,stirring speed is 300r/min,catalyst to oil ratio is 1：300,the acid of the waste gasoline engine oil fell to 0.0295 mgKOH/g from 0.5195 mgKOH/g,deacidification rate reach to 94.36%.We can use diethylenetriamine to removal the acid of different waste oil,and clay refining,various physical and chemical indexes of the waste oil obtain good improvement.
