PURPOSE:To obtain the subject composition, consisting of a specific compound and tetrafluoroethane, excellent in solubility and stability and capable of preventing friction, abrasion and seizure in sliding parts of compressors. CONSTITUTION:The objective composition consisting of (A) a compound expressed by formula [X is halogen; R<1> is hydrocarbon; R<2> and R<3> are H or lower alkyl; n is a positive number so as to provide the compound expressed by the formula with 10-300cst viscosity (40 deg.C)] and (B) 1,1,1,2-tetrafluoroethane. Furthermore, the weight of the components (A) to (B) is preferably (5/95)-(60/40). |
