| titleOfInvention | Production of macrocyclic ester |
| abstract | PURPOSE: Polyester from dibasic acid and alkylene glycol is subjected to depolymerization and cyclization under reduced pressure in the presence of a specific additive to reduce the viscosity of the reaction mixture, smoothen the reaction progress and give title compound in a short time in high yield. n CONSTITUTION: The depolymerization and cyclization of polyester of formula I (n is 6W14; m is 2W8), resulting from polycondensation reaction between dibasic acid such as suberic acid and alkylene glycol such as ethylene glycol, is effected under reduced pressure, wherein at least one selected from polyoxyalkylene glycol, polyoxyalkylene glycol ester, monobasic acid, monobasic acid ester, monobasic anhydride, monohydric alcohol and monohydric alcohol ester is added to the reaction mixture to form the macrocyclic ester of formula II. n EFFECT: The products are free from trace amounts of impurities. n USE: Musk perfume. n COPYRIGHT: (C)1980,JPO&Japio |
