Study on Light Oxidative Mechanism of Hydro-treated Naphthenic Lube base Oil under Ultraviolet Radiation

摘要：

In this paper, Taking use of KN4010 as base stock, Iodometry and Infrared Spectroscopy (IR) were carried out to monitor its change of peroxide value and oxygen-containing compounds against time under ultraviolet radiation, and oxidative mechanism of hydrotreated lube base oil was researched in detail. The results of test indicate its light oxidative mechanism conforms to the radical reaction theory which is in the medium oxidative stage. Peroxide value shows the oil sample is very sensitive to ultraviolet light. The content of carbonyl compounds and hydroxyl compounds show a decrease trend and the content of hydroxyl compounds indicative almost unchangeable under ultraviolet radiation. No organic acid and ester is found under oxidative process.
