Study on Properties and Application of Domestic AN-5 Alkyl Naphthalene
To expand the application fields of alkyl naphthalene,this study respectively analyses the physicochemical proper-ties of domestic AN-5 alkyl naphthalene and the application of American Petroleum Institute(API)Ⅲ6 base oil partial re-placed by it in the field of gasoline engine oils and anti-wear hydraulic oils.Evaluations were conducted on physicochemical properties,high-temperature coking resistance,oxidation stability,thermal stability,and hydrolytic stability.The results show that the infrared spectrum of domestic AN-5 alkyl naphthalene is essentially consistent with that of imported alkyl naphthalene,exhibiting outstanding antioxidant performance.Gasoline engine oils(5W-30 and 5W-40)formulated with domestic AN-5 alkyl naphthalene as a 10％replacement for API Ⅲ6 base oil meet the required specifications and improve coking resistance,as proved by a significant reduction in coking area and weight on aluminum plates after the inclined plate gelling test.The formulated L-HM 32 anti-wear hydraulic oil(high pressure)also meets the required physicochemical properties while enhancing hydrolytic stability,oxidation stability,and thermal stability of the hydraulic oil.
