A biased acid site distribution in mordenite (MOR), which refers to the enrichment of acid sites within 8-membered ring (MR) channels, was observed with the addition of N-methyl-2-pyrrolidone (NMP) in the initial gel and verified by the enhanced activity in dimethyl ether (DME) carbonylation reaction. This is the first time that lactam has been proved effective in regulating acid site distribution, and the possible mechanism was investigated.

N-甲基-2-吡咯烷酮对MOR中Al分布和DME羰基化反应活性增强的影响

通过在初始凝胶中添加N-甲基-2-吡咯烷酮 (NMP)观察到丝光沸石 (MOR) 中的偏酸位点分布，即在 8 元环 (MR) 通道内富集酸位点。通过在二甲醚 (DME) 羰基化反应中增强的活性来验证。这是首次证明内酰胺可有效调节酸位点分布，并对其可能的机制进行了研究。
