titleOfInvention |
Use of ester compounds in lubricating oil compositions |
abstract |
Ester compounds possessing heat stability in the presence of a metal and prepared from di- to nona- hydric hindered alcohols having 5 to 15 carbon atoms and saturated aliphatic monocarboxylic acids having 3 to 20 carbon atoms or derivatives thereof, characterized in that the proportion of the branched carboxylic acids or derivatives thereof in all the carboxylic acids or derivatives thereof is at least 50 % by mole and the ester compounds have a hydroxyl value of at most 30 mg KOH/g and an acid value after the sealed tube test of at most 10 mg KOH/g: and a lubricating oil composition characterized by containing at least 20 % by weight of the ester compounds. Thus the invention provides ester compounds possessing excellent heat stability in the presence of a metal, and a lubricating oil composition and a hydraulic fluid composition for refrigerators, each composed mainly of the ester compounds. |
