概述了影响环烷基白油光安定性的主要原因。采用了溶剂精制和络合精制组合方法,对白油光安定性进行了研究。实验结果表明,在络合剂4%,溶剂萃取的剂油比为6∶1,反应温度80℃的条件下白油光安定性良好,满足白油的光安定性要求。初步研究结果表明:影响白油光安定性的主要原因是碱性氮化物。
The main reasons that affect the light stability of naphthenic white oil are summarized. Solvent refining and complexing combined methods were used to study the light stability of white oil. The experimental results show that under the conditions of 4% complexing agent, 6% solvent-to-oil ratio and 80 ℃ reaction temperature, the light stability of white oil is good and the light stability of white oil is satisfied. The preliminary results show that the main reason for the light stability of white oil is alkaline nitrides.
