| abstract |
A refrigerator oil composition is described, comprising: (1) at least one of mineral oil and synthetic oil and (2) at least one of (a) 15-crown-5, (b) a derivative of 15-crown-5, and (c) a glycidyl compound represented by the general formula: <IMAGE> (wherein R is hydrogen or an alkyl group containing from 1 to 5 carbon atoms). This composition exhibits high stability when in contact with halogen-containing refrigerants and is limited in the formation of hydrogen chloride, for example, resulting from its reaction with the halogen-containing refrigerants. Thus the refrigerator oil composition of the invention is useful as a lubricant for refrigerators. |
