Abstract
An improved process for producing a macrocyclic ester compound comprises decomposing and cyclizing linear ester compounds, from high to low condensate, to the macrocyclic ester, with the addition of glycol or oligoester compound of which the component is similar as those of said linear ester compounds. By this addition the reaction proceeds easily for a long time, and its efficiency is improved.
