摘要： The invention concerns a method for producing diaryl carbonates from monophenols and phosgene or chloroformic acid aryl esters in the presence of an 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 crystallization and recovered.
摘要翻译： 本发明涉及在任选取代的吡啶或其盐酸盐作催化剂存在下，从单酚和光气或氯甲酸芳酯生产碳酸二芳基酯的方法，并将其回收和再注入该方法。 该方法至少部分地在液相中进行，而不使用另外的溶剂，催化剂通过结晶分离并回收。
