摘要: For the first time, kinetics and mechanism of reaction between 4-methyl-benzaldehyde, 4-bromoaniline methyl acetoacetate is spectrally investigated in presence La(NO3)3.6H2O as a catalyst. Based on experiment data, overall order two. The second-order rate constant dependency temperature was agreement with Arrhenius Eyring equations. kinetic thermodynamic parameters have been calculated. Furthermore, useful information obtained from studies effect solvent concentration reactants rate. results showed that second step rate-determining (RDS). proposed also confirmed according to steady state approximation.
