Abstract
PURPOSE:To provide a rotary refrigerator oil having improved heat resistance and abrasion resistance, composed of a lubricating oil, a hindered phenol, an aromatic amine, tocopherol, a phosphorous acid ester and a phosphoric acid ester. CONSTITUTION:The title oil is prepared by adding (A) 0.01-100 parts by weight of one or more compounds selected from (a) a monocyclic or polycyclic phenol of formula I (R1,2 are H, CH3, C2H5, etc.; R3 is H, CH3, OCH3, etc.; A is 1-20C hydrocarbon group), etc., (b) an aromatic amine of formula II (R1, R1', R2, R2' are CnH2n+1, OCOCnH2n+1; n is 0-20), etc., (c) a compound of formula III (R1,2 are CnH2n+1; n is 0-20), etc., (d) tocopherol, and (e) a phosphorous acid ester or phosphoric acid ester of formula IV (R1, R2, R2' are CnH2n+1; n is 0-20), to (B) 100 parts by weight of a lubricating base oil having a iodine value of >=1.0 and obtained by the hydrogenation treatment.
