Document Type and Number:

WIPO Patent Application WO/1996/001301

Kind Code:

A1

Abstract:

A lubricating oil containing an aromatic ether compound represented by the general formula (R1)nPh-O-(R2O)mR3, wherein nR1s represent each independently a specified hydrocarbon group, a hydrocarbon group having an ether linkage, or a hydrocarbon group having an alkoxy group or a halogen atom; mR2s represent each independently a C2-C4 alkylene group; R3 represents a C1-C12 hydrocarbon group; Ph represents an aromatic substituent; n represents an integer of 1 to 5; and m represents an integer of 1 to 30. This oil is excellent in lubricity, cleanness and electrical insulation, has a high viscosity and excellent sealing and antiwear characteristics, and is excellent in compatibility with R-134a and the like. Hence it is suited for use as a lubricant for refrigerators using R-134a as the refrigerant, such as electric refrigerators and room air-conditioners.
