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 C¿2?-C4 alkylene group; R?3¿ represents a C¿1?-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.

Abstract: The present invention provides lubricant oil compositions comprising a polyalkylene glycol polycarbonate. The lubricant oil compositions are useful for industrial gear oil, automotive gear oil, and lubricant oil for refrigerators, rolling installations and fibers, which are excellent in lubricating properties and detergency. The present invention also relates to lubricant oil compositions which comprise a polyalkylene glycol polycarbonate having mutual solubility with an ozone layer-nondestructive Freon such as Freon R-134a, and which are accordingly especially suited for refrigerators using hydrogenated fluorocarbon as a refrigerant. A polyalkylene glycol polycarbonate according to the invention comprises a polyoxypropylene group in the molecular chain and an alkyl group and an alkyloxyalkylene group at the molecular terminals. This invention provides a process for preparing said polyalkylene glycol polycarbonate wherein a polypropylene glycol and a carbonate are allowed to react, said reaction including condensation polymerization. The invention also provides a process without condensation polymerization for preparing a polyalkylene glycol polyol wherein a polyol and a carbonate is allowed to react in the presence of a basic catalyst while a produced alcohol is being distilled off, the catalyst is removed then, and the unreacted carbonate is eliminated.
