Abstract
4-(2,2,2-Trifluoroethoxy)nitrobenzene was used as raw material to create a reaction for 1 h at 70 °C by using ethanol and palladium carbon as solvent and catalyst, respectively, to obtain the desired product 4-(2,2,2-trifluoroethoxy)aniline with 97 % yield and 99.9 % purity. NMR, IR, MS, GC and other analysis and detection methods were used to conduct qualitative and quantitative analyses of the desired product. This paper discussed the process conditions of hydrogenation and reduction reaction and mainly investigated the impact of dosage and recycling of catalyst.
