The complex made up of the nitrogen large ring and cerium(III)ion was used for catalytic hydrolysis of the bis(p-nitrophenyl)ester phosphate(BNPP)in the paper.The rate of the catalytic reaction was studied following the change of the pH and temperatures in the reaction solution.This reaction was considered to be apparent-first-order reaction because the nitrogen large ring cerium complexes concentration was ten times greater than that of the BNPP in all reactio system.The results of the study indicated that the most comfortable temperatures was 45℃,pH was 8.0.

The catalytic hydrolysis of bis(p-nitrophenyl)ester phosphate by nitrogen large ring cerium complexes occurs at 45°C and 8.0 pH, with the most comfortable conditions being 45°C and 8.0 pH.
