对-正丁基苯胺合成过程中绿色催化剂的初选

Preliminary Selection of Green Catalyst for Synthesis of p-Butyl Aniline

以正丁醇和苯胺为反应物,分别选择碘化钠、碘化钾、碘的乙醇溶液为催化剂,在均相反应器中催化合成对-正丁基苯胺,产物用薄层层析色谱和气相色谱进行检测。结果表明:碘化钠、碘化钾、碘的乙醇溶液为催化剂时均可合成对-正丁基苯胺,其中以碘化钾作催化剂时的产率最高,达到25.63%。

p-Butyl aniline is synthesized using n-butanol and aniline as reactants with NaI,KI,ethanol solu- tion of iodine as catalyst, respectively. The results show that the three kinds of catalysts all can catalyze the al- kylation to get p-butyl aniline,and the yield of p-butyl aniline reaches the highest of 25.63% when KI is used as catalyst.
