| Abstract: | A kinetic study on ethanol carbonylation over Ni-Pb/C catalyst was carried out in a differential reactor under atmospheric pressure and at reaction temperature of 250 C, with CO/C2H5OH/C2H5I= 2/1 /0. 1 and contact time (W/F) of 3. 3 g.h/mmol. The rate equation for ethyl propionate formation is as follows with activation energy of 43. 8 kJ /mol: The rate equation for the side reaction --ether formation of as follows with activation energy of 28. 9 kJ /mol: |
