| titleOfInvention | Method for producing alkylene oxalate cyclic ester and purification method |
| abstract | (57) [Summary] (Modified) [PROBLEMS] To provide a method for economically and efficiently producing a cyclic ester from an oligomer of alkylene oxalate. In the method for producing an alkylene oxalate cyclic ester by depolymerizing an alkylene oxalate oligomer, (1) an alkylene oxalate oligomer and 2 A mixture containing at least one high-boiling polar organic solvent having a boiling point in the range of 25 to 450 ° C. is heated under normal pressure or reduced pressure to a temperature at which depolymerization of the oligomer occurs (2) the oligomer. The oligomer is dissolved in the solvent until the residual ratio of the melt phase of 0.5 becomes 0.5 or less, (3) Continue heating at the same temperature to depolymerize the oligomer in the solution phase, (4) distill the formed cyclic ester together with the solvent, and (5) recover the cyclic ester from the distillate. A method for producing an alkylene oxalate cyclic ester, comprising: |
