Beschreibung
Zusammenfassung:	PURPOSE:To obtain the title composition excellent in refrigerant stability and fluid film breaking resistance at high temperatures by using a heavy branched alkylbenzene as a base oil and mixing this oil with a specified naphthenic mineral oil. CONSTITUTION:95-80wt.% heavy branched alkylbenzene based on a dialkylbenzene produced as a by-product in, for example, the synthesis of a monoalkylbenzene, desirably, a dialkylbenzene having 12-36 carbon atoms on the average in the molecule and having an alkyl group such as a group of the formula (wherein n >= 1) composed of an alkyl group as the main chain to which the second alkyl groups such as a methyl group is attached is used as a base oil and this base oil is mixed with 5-20wt.% naphthenic mineral oil containing 0.03-0.1% S and 5-15ppm of N so that the obtained mixture may have a kinematic viscosity of, desirably, 8-70cSt.
