Abstract
A refrigerator oil composition with a base oil (A), and a first phosphorus compound (B). The first phosphorus compound (B) is a first phosphite ester (B1) represented by formula (1) and a second phosphite ester (B2) represented by formula (2): A method of producing a refrigerator oil composition by mixing a base oil (A) with a first phosphorus compound (B). A refrigerator mixture composition includes the refrigerator oil composition and a refrigerant.
Claims11
A refrigerator mixture composition, comprising:
- a refrigerant;
- and
- a refrigerator oil composition, comprising:
- a base oil (A);
- a first phosphorus compound (B);
- and
- a second phosphorus compound (C),
- wherein the base oil (A) comprises at least one type of base oil (A2) selected from the group consisting of a polyalkyleneglycol and a polyvinylether,
- wherein the content of the base oil (A2) is 50 to 100% by mass based on the total amount of the base oil (A),
- wherein the first phosphorus compound (B) is a reaction product of bis [2,4-bis(2-methylbutane-2-yl)phenyl]4-(2-methylbutane-2-yl)phenyl phosphite, 2,4-bis(2-methylbutane-2-yl)phenylbis [4-(2-methylbutane-2-yl)phenyl]phosphite, and tris [4-(2-methylbutane-2-yl)phenyl]phosphite,
- wherein the content of the first phosphorus compound (B) is 0.3 to 0.5% by mass based on the total amount of the refrigerator oil composition,
- wherein the second phosphorus compound (C) is at least one selected from the group consisting of a phosphoric acid compound (C1) and an organic phosphine oxide compound (C2), and
- wherein the content of the second phosphorus compound (C) is 0.5 to 0.9% by mass based on the total amount of the refrigerator oil composition.
