发明名称 Process for the preparation of diaryl carbonates
摘要 A process and a catalyst for the homogeneous liquid phase reaction of aromatic haloformates with aromatic hydroxy compounds for the production of diaryl carbonates with the elimination of anhydrous hydrogen halide. The catalysts of the present invention comprise at least one aromatic heterocyclic nitrogen compound. These catalysts permit the production of the products in very high yield, and the reaction proceeds at high rates.
