Title:
REFRIGERATOR OIL COMPOSITION AND MIXED COMPOSITION FOR REFRIGERATORS
Document Type and Number:
WIPO Patent Application WO/2023/100935
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a refrigerator oil composition which has a proper melt viscosity when a hydrocarbon-based refrigerant is dissolved therein, and has low hydrocarbon-based refrigerant solubility; and a mixed composition for refrigerators, which comprises the refrigerator oil composition. The problem is solved by a refrigerator oil composition which is used for a refrigerant comprising a hydrocarbon-based refrigerant and which contains at least one component selected from polyalkylene glycol-based compounds (A) each represented by general formula (1) and each having a number average molecular weight of 1,100 or more. [In general formula (1), one of R1 and R2 represents a hydrogen atom and the other represents a linear or branched alkyl group having 1 to 16 carbon atoms inclusive; E represents an ethylene group; P represents a propylene group; and m and n independently represent a numerical value of 0 or more, in which m + n is 1 to 50 inclusive.]
