【摘要】 以Ｐｄ／Ｃ为催化剂，以ＮａＩ为助催剂，以无水乙醇为溶剂，进行了苯胺氧化羰基化反应。研究了苯胺氧化羰基化的最佳工艺条件，解释了碘化钠在本反应中所起的助催作用。在１７０℃，反应两小时后，Ｐｄ／Ｃ显示了高活性（９７.４９％）和高选择性（８５．２６％）。最后，提出了苯胺氧化羰基化反应的机理。更多还原

【Abstract】 The oxidative carbonylation of aniline to carbamate over Pd-based catalyst was studied by using NaI and absolute ethanol as the promoter and solvent, respectively. The optimum process conditions for this reaction were investigated. At 170 C, after 2 h of reaction, the Pd/C catalyst exhibited high activity (97.49%) and high selectivity (85.26%). The promoter role of NaI was discussed, and a mechanism for the title reaction was proposed.更多还原
