| Abstract: | Synthesis of ethyl acetate catalyzed by carbon nanotubes which treated by liquid-phase oxidation was studied.The best reaction conditions are as follow: ratio of alcohol to acid is 2.5∶1,level of catalyst is 1.5 g(about 0.2 mol acetic acid),the reaction time is 2.5 h,and the best temperature is around 92℃.The results showed the conversion of acetic acid more than 58 percent.The catalyst is not corrosive for the device,recycle,and products form is simple.It is a green route to the synthesis of ethyl acetate. |
