Abstract

The mechanism of Bis(p-nitrophenyl) phosphate ester(BNPP) catalyzed by the system of diethylenetriamine and yttrium ion was investigated.The catalytic efficiency and stability of the system was studied in different reaction conditions.The results indicated that the catalytic system exhibited high activity,stability and reproducibility under pH 7.8～9.3 and temperature 25～50 ℃.The results also showed that the active species is the complex of Y3+ ion and diethylenetriamine.
