| 摘 要： | 本文利用含氮不饱和大环铈配合物催化BNPP水解。通过改变温度、pH等方法测定含氮大环铈配合物催化对硝基苯酚磷酸二酯的反应速率。整个实验过程保持含氮大环铈配合物浓度高于底物浓度10倍以上,以使反应为一级反应。结果表明:其水解反应的最佳温度在45℃左右,最佳pH在8.0左右。

| Abstract: | 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. |
