Abstract

See full text

The present invention provides a mixed ester of pentaerythritol or a mixed polyhydric alcohol and carboxylic acids; the mixed polyhydric alcohol consisting of pentaerythritol and dipentaerythritol represented by formula (I), and the carboxylic acids comprising 3,5,5-trimethylhexanoic acid and 2-propylheptanoic acid. The mixed ester exhibits excellent properties (e.g., miscibility with a refrigerant that comprises fluoropropene, low-temperature properties, oxidation stability, oxidation-hydrolysis stability, and lubricity) in a well-balanced manner while having the viscosity within the range required for a refrigerant oil, and may be used in an industrial lubricant (e.g., refrigerant oil) and the like.
