发明名称 Ester for refrigerator oils and method for producing same
摘要 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.
