Abstract

PURPOSE: A lubricant oil that contains a specific diphenyl ether substituted with polyalkyls as the effective component, thus showing high heat and oxidation resistance, resisting the conversion into sludge even at high temperatures and having low evaporation loss, high flash point, high viscosity and low pour point.
CONSTITUTION: Said lubricant oil contains, as the effective component, polyalkyl- diphenyl ether bearing 3 or more alkyl groups of 10W20 carbon atoms and, when necessary, a thickener as polybutene. The polyalkylated diphenyl ether is obtaind, e.g., by reaction of diphenyl ether with and α-olefin in the presence of anhydryous aluminum trichloride.
EFFECT: The resulting lubricant does not form sludge for more than 5 days at 170°C and has a flash point over 300°C and pour point of -37.5W40°C.
