ABSTRACT:
A diester represented by the formulawherein A represents a cyclohexane ring, cyclohexene ring or benzene ring, X is H or methyl group, RXand RYare the same or different and each is C3-C18 branched-chain alkyl group, C1-C18 straight-chain alkyl group, C2-C18 straight-chain alkenyl or C3-C10 cycloalkyl, provided that when A is a benzene ring, RXand RYare different from each other and —COORXand —COORYare attached to two adjacent carbon atoms of the benzene ring, and having the following properties:1) a total acid number of 0.05 mgKOH/g or less,2) a sulfated ash content of 10 ppm or less,3) a sulfur content of 20 ppm or less,4) a phosphorus content of 20 ppm or less,5) a peroxide value of 1.0 meq/kg or less,6) a carbonyl value of 10 or less;7) a volume resistivity of 1×1011Ω·cm or more,8) a hydroxyl value of 3 mgKOH/g or less, and9) a water content of 100 ppm or less,a process for preparing the same and a refrigerator lubricating oil comprising the diester.
