Summary: | The present invention provides a method for producing a high quality ester and an ester obtained by this method. The method includes reacting an alcohol with a carboxylic acid in a presence of a Lewis acid catalyst in an amount of 0.00001 to 0.006 mol and a phosphorus-containing reducing agent in an amount of 0.0003 to 0.005 mol with respect to one mol of carboxyl groups of the carboxylic acid, and separating a resultant ester. This ester is useful as ester lubricating base stock for grease, automotive engine oil, and refrigerating machine oil. |
