利用固体核磁共振方法，研究了铜修饰丝光沸石(Cu-H-MOR)分子筛催化甲醇(CH3OH)与一氧化碳(CO)羰基化反应过程。通过研究反应过程中生成的各吸附物种与 Cu2+的相互作用，分别对这些吸附物种进行了归属，确定了铜甲氧基(Cu-OCH3)和铜乙酰基(Cu-(CO)-CH3)为羰基化反应过程的中间产物，讨论了可能的反应机理。

Carbonylation of methanol with CO on Cu-H-mordenite (Cu-H-MOR) zeolites was studied by 13C solid-state NMR spectroscopy. By characterizing the interaction between adsorbed species and Cu2+ cations, we determined copper methoxy group (Cu-OCH3) and copper acetyl group (Cu-(CO)-CH3) as the intermediates of this reaction. The possible mechanisms of carbonylation reaction of methanol with CO on Cu-H-MOR zeolites were discussed.
