摘要：
본발명은촉매로서하나이상의임의적으로치환된피리딘또는그의히드로클로라이드염의존재하에서모노페놀및 포스겐또는클로로포름산아릴에스테르로부터디아릴카르보네이트의제조방법, 그의방법으로의회수및 재주입에관한것이다. 본방법은추가적인용매의사용없이적어도부분적으로액체상에서수행되고, 촉매는증류에의해분리되고회수된다.
摘要（英）：
The invention concerns a method for producing diaryl carbonates from monophenols and phosgene or chloroformic acid aryl esters in the presence of at least one optionally substituted pyridine or the hydrochloride salt thereof as catalyst, and the recovery and reinjection thereof back into the method. The method is carried out at least partially in a liquid phase without the use of an additional solvent, the catalyst being separated by means of distillation and recovered.
