| 发明名称 | Pentaerythritol tetraester | ||
| 摘要 | A pentaerythritol tetraester which is a mixed ester of pentaerythritol and carboxylic acids is provided, wherein the carboxylic acids consist of isobutyric acid and 3,5,5-trimethylhexanoic acid and the molar ratio of isobutyric acid to 3,5,5-trimethylhexanoic acid in the carboxylic acids is 36/64 to 80/20. The pentaerythritol tetraester may be used in a refrigerant oil or the like which exhibits excellent miscibility with a difluoromethane refrigerant among other properties. | ||
