| Abstract: | Two aza crown ether substituted unsymmetry bis-Schiff base transition-mental complexes have been used as mimic hydrolytic enzyme model catalyzing carboxylic acid esters (PNPP) hydrolysis. The kinetics on PNPP hydrolysis catalyzed by these complexes are investigated. The kinetic mathematical model of PNPP cleavage catalyzed by these complexes is proposed. The results show that the rate for the catalytic PNPP hydrolysis is increased following the increase of pH of the buffer solution; four complexes exhibite high activity in the catalytic PNPP hydrolysis. |
