    摘要： 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.

    摘要： A method for producing 3,5,5-trimethylhexanal by allowing diisobutylene (DIB), carbon monoxide and hydrogen to react with one another in the presence of a cobalt-based catalyst, comprising: a step of allowing DIB to react with carbon monoxide and hydrogen in the presence of a cobalt-based catalyst until a convention of DIB reaches 50 to 85% (first stage reaction step); a step of separating unreacted DIB from a reaction product obtained in the first stage reaction step (unreacted DIB separation step); and a step of allowing the unreacted DIB separated to react with carbon monoxide and hydrogen in the presence of a cobalt-based catalyst (second stage reaction step).
