Usage

Purification Methods

Wash the ester with aqueous Na2CO3 then shake it with water. Ether is added to break the emulsion, and the solution is washed twice with water, and dried (CaCl2). After evaporating the ether, the residual liquid is distilled three times under reduced pressure. It is stored in a vacuum desiccator over P2O5. [Beilstein 9 IV 3183.]

Dicarboxylic diester, process for producing the same, and refrigerating machine lubricating oil comprising the ester

A diester represented by the formula wherein A represents a cyclohexane ring, cyclohexene ring or benzene ring, X is H or methyl group, RX and RY are 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-C18 cycloalkyl, provided that when A is a benzene ring, RX and RY are different from each other and —COORX and —COORY are 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 1×1011 Ω·cm or more, 8) a hydroxyl value of 3 mgKOH/g or less, and 9) a water content of 100 ppm or less, a process for preparing the same and a refrigerator lubricating oil comprising the diester.
