专利号:US-4041068-A 优先权日:1976-06-29 标题:Synthesis of oxalate esters by catalytic oxidative carbonylation of borate esters 发明人:ZEHNER LEE R; ZAJACEK JOHN G 权利人:ATLANTIC RICHFIELD CO 摘要:A process for the preparation of oxalate esters by the catalytic oxidative carbonylation of orthoborate, metaborate and polyborate esters or mixtures thereof with carbon monoxide and oxygen or an oxygen-containing gas in the presence of a metal salt catalyst, an amine base and at least a catalytic amount of an alcohol. Preferably a catalytic amount of particular metal oxidizing salts are employed along with a catalytic amount of an amine salt compound which may be formed in situ by the addition of an acid. Alternatively various counterions and ligands of the metal salt catalysts may be employed.
