Abstract
PURPOSE: To provide titled ester oil having increased stability to flon and useful for use in refrigerators, coolers, flon turbines, etc., by a method wherein a specified amount of a phosphite is added to a polyhydric alcohol ester or a dibasic acid ester.
CONSTITUTION: 0.02W5wt% of a phosphite of formula I (wherein R1, R2 are alkyl, alkenyl, phenyl) (e.g. the cpd. of formula II) is added to a polyhydric alcohol ester (e.g. an ester devived from an aliph. monocarboxylic acid and a polyhydric alcohol such as neopentyl glycol or trimethylolpropane) or a dibasic acid ester (e.g. an ester derived from a monohydric alcohol and an aliph. dicarboxylic acid such as adipic acid or suberic acid) to obtain title oil. The phosphites having R1 and R2 groups of 6W18 carbon atoms are preferred.
