    • A process for producing a carbonic ester, characterized in that an aromatic monohydroxy compound or an aliphatic monohydroxy compound is subjected to oxidative carbonylation with carbon monoxide and oxygen in the presence of a palladium catalyst using a compound having a carbonate bond as a reaction solvent. A process for producing a polycarbonate, characterized in that an aromatic dihydroxy compound or an aliphatic dihydroxy compound is subjected to oxidative carbonylation with carbon monoxide and oxygen in the presence of a palladium catalyst using a compound having a carbonate bond as a reaction solvent is also described. The carbonic ester can be produced with a higher yield and at a higher reaction rate and, also, a polycarbonate having a higher molecular weight as compared with the conventional method can be produced with a higher yield and at a higher reaction rate.
    • 一种碳酸酯的制造方法,其特征在于,在钯催化剂存在下,使用具有碳酸键的化合物作为反应溶剂,将芳香族单羟基化合物或脂肪族单羟基化合物与一氧化碳和氧进行氧化羰基化反应。 还描述了一种制备聚碳酸酯的方法,其特征在于芳族二羟基化合物或脂族二羟基化合物在钯催化剂存在下用一氧化碳和氧气进行氧化羰基化,其中还描述了使用具有碳酸酯键的化合物作为反应溶剂 。 可以以更高的产率和更高的反应速率制备碳酸酯,并且与常规方法相比,也可以以更高的产率和更高的反应速率制备具有较高分子量的聚碳酸酯。
