摘要
分析了酸性白土在润滑油白土精制过程中对油品的氧化机理。根据小型试验和工业生产数据，提出了真空脱氧是消除精制过程中油品氧化增色的有效途径。
The mechanism by which the basic lube is Oxidized in the course of white soil refining was anaslysed.In terms of the small-scale experiments and the date of the production,it was put forward that vacuum deoxidizing is the effective method for prevenf from Oxidation and the encolouration of the basic lube in white soil refining.
