| Abstract: | The kinetics about hydroesterification of ethylene with methyl formate in RuCl_3 catalyst system was studied. The effect of mass transfer on the reaction was eliminated through using suction turbine impeller. The reaction mechanism was discussed and the kinetic equation was deduced as r_p=k_1C_(M_0)C_A/(1-1/β)]1-(C_A/C_(A_0))~((β-1))]. Rate constant (k_1) and active energy(E) obtained from the experiments are 0.0668mol/(s·L) and 81.363 kJ/mol, respectively. |
