【Abstract】 The dehydrogenation mechanism of ethanolamine on Raney Copper catalyst have been studied in this paper. A rate equation for the reaction was derived as r=kc A. The activation energy E a for the reaction is 147.80kJ/mol, and the relation between the rate constant k and reaction temperature T is revealed as k=6.8111×10 15 exp(-147.80×10 3/ RT) . Based on the equation, the average deviation of conversion between the experimental data and calculated values was about 1.25%.更多还原
