Abstract: The present invention relates to an ester for refrigerator oils having less remaining by-products in the ester and having high thermal stability, and a method for producing the ester for refrigerator oils. The ester for refrigerator oils is obtained by treating a crude ester product, which is obtained by reacting a neopentyl polyol having a carbon number of 5 to 10 with an aliphatic carboxylic acid having a carbon number of 4 to 12, with one or more kinds of salts selected from the group consisting of sulfite, bisulfite, and pyrosulfite.

Abstract: It is provided an ester for a refrigerator oil and of mixed alcohols and mixed monocarboxylic acids. The mixed alcohols include dipentaerythritol and tripentaerythritol in a mass ratio of 90/10 to 99.7/0.3, and the mixed monocarboxylic acids include n-pentanoic acid and 2-methyl butanoic acid in a mass ratio of 50/50 to 80/20. The ester has a kinematic viscosity of 50 to 150 mm2/s at 40° C.
