新农药吡虫啉水解动力学和机理研究
- Kinetics and mechanism of pesticide imidacloprid hydrolysis
- 摘要：介绍了吡虫啉在不同酸、碱条件下的降解动力学情况。实验表明,吡虫啉在酸性、中性条件下比较稳定,不易水解,而在碱性条件下水解速度较快。通过对水解产物的鉴定,确定了水解产物主要是1 (6-氯-3 吡啶甲基)-2 咪唑酮,从而推测了有关吡虫啉的水解机理。
- Abstract：Kinetics of imidacloprid hydrolysis were studied at various pH values.The experimental results show that imidacloprid is stable in acid and neutral water and its hydrolysis easily takes place in basic water.By extracting and analyzing hydrolysis products,it was found that the primary hydrolysis product is 1 [(6 chloro 3 pridinl)methyl] 2 imidazolidone.The hydrolysis mechanism of imidacloprid is thus proposed.
- Key words：hydrolysis imidacloprid
