A STUDY ON THE OXIDATIVE CARBONYLATION OF ANILINE

Abstract

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。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
