Document Type and Number:
WIPO Patent Application WO/1997/010319
Kind Code:
A1
Abstract:
A lubricating oil composition characterized by containing phosphorus compounds having groups wherein hydroxyl groups are bonded to respective adjacent carbon atoms; and a hydraulic fluid composition for refrigerators characterized by containing hydrofluorocarbons and a lubricating oil composition prepared by blending the above phosphorus compounds with a lube base oil mainly comprising oxygen compounds. These compositions are excellent in lubricity and do not corrode metals.
