Mechanism study on Raney nickel-catalyzed amination of resorcinol
Ge, Xin,Pan, Jiong-Bin,Qian, Chao,Feng, Lie,Chen, Yun-Bin,Chen, Xin-Zhi
, p. 201 - 207 (2014)
Amination of resorcinol catalyzed by Raney nickel has been examined with good yield. Using the first principle density functional theory, some detailed mechanism of the amination of resorcinol on the Ni(111) surface is explored. The resorcinol is adsorbed on the Ni surface at the hollow site to form ketone by isomerization. The isomerization has a barrier of 122.1 kJ/mol. Ketone can couple with secondary amine mediated by resorcinol to afford hemiaminal. For the formation of hemiaminal, the steric effect of the alkyl group of secondary amine is obvious. Hemiaminal undergoes dehydration to get final product, which occurs by the preferred adsorption in the bridge site, cleavage of CO bond initially, followed by subsequent cleavage of CH bond.
Method for synthesizing M-diethylaminophenol
-
Paragraph 0016-0020, (2021/01/15)
The invention provides a method for synthesizing m-diethylaminophenol. The method comprises the following steps: mixing potassium hydroxide and magnesium oxide, and calcining at 700-800 DEG C to obtain a solid super base catalyst; adding sodium amide and the solid super base catalyst into diethylamine, stirring, keeping the temperature at 3-8 DEG C, dropwise adding o-chlorophenol within 20 minutes, stirring for 10-20 minutes after dropwise adding is finished, starting ultrasonic oscillation, heating, carrying out reflux reaction for 10-30 minutes, carrying out reduced pressure rotary evaporation to recover diethylamine, adding xylene, stirring, cooling to 5 DEG C or below, and adding water to quench the catalyst; and adjusting the pH value of a water layer to be neutral or weakly acidic, and recovering xylene to obtain the m-diethylaminophenol finished product. The method disclosed by the invention not only is short in time and high in efficiency, but also does not use expensive m-aminophenol raw materials, so that the problem of troublesome post-treatment is solved; meanwhile, potential safety hazards caused by using unsafe catalysts can be avoided, so that m-diethylaminophenol production is safer, more economical and more efficient, and industrialization is better facilitated.
