摘要：
Aromatic carbonates useful for the preparation of high molecular weight polycarbonate resins are prepared by reacting methanol, carbon monoxide and oxygen to prepare dimethyl carbonate; reacting a methyl silyl ether with a phenol or bisphenol to prepare an aryl silyl ether, and reacting the dimethyl carbonate and aryl silyl ether to prepare an aromatic carbonate.
