(57) [Summary] (Revised) [Objective] To provide a method capable of easily producing the required esters in good yield. [Structure] R 3 X + R 4 COOM → R 3 O—CO—R 4 (wherein R 3 and R 4 are alkyl groups, X is halogens, M Indicates one metal selected from sodium, potassium and lithium. ) In the method for producing an ester in which the reaction represented by the reaction formula is performed, the catalyst represented by the following general formula (1) (In the formula, R 1 and R 2 are an alkyl group or hydrogen, and n is 4 Is an integer of 8 and m is a real number of 0 to 20, respectively. ) A method for producing an ester, which comprises using a calixarene-polyethylene glycol condensate represented by |
