Abstract: PURPOSE:To obtain the title compound useful as musk perfumes, in a simple process in high yield, by polymerizing a dibasic fatty acid with ethylene glycol in the presence of an aluminum compound having a carbonate radical, and by depolymeirzing and ring closure of the polymer in vacuo. CONSTITUTION:A basic aqueous solution of an aluminum compound, e.g. Al(OH)3, is brought into contact with CO2 gas or a substance which produces CO2 gas, to give an aluminum compound having a carbonate radical. A dibasic fatty acid of formula I: (n is an integer 6-14) or its ester is polymerized with ethylene glycol or ethylene oxide in the presence of the aluminum compound thus obtained at 50-250 deg.C, preferably 100-200 deg.C, and subjected to depolymerization and ring closure at 180-300 deg.C, preferably 240-280 deg.C, at a pressure of 10 - 10 mm Hg, preferably 10-1-l mm Hg, to give a large ring ethylenedioate of formula II.
