摘要: 通过计算蓖麻碱的基本量子化学参数和分析蓖麻碱分子的键能,探索除去蓖麻碱分子上氰基团的改性方法。在加入浓盐酸,微波功率600W,微波温度150℃,微波辐射4.5h的条件下,蓖麻碱分子上的氰基团被成功的去除。蓖麻碱改性后杀虫作用下降表明氰基团在蓖麻碱的杀虫作用中起了很重要的作用。

Abstract:

To find out the modification method for removing the cyanogens group of ricinine, the basic quantum chemistry parameter of ricinine was calculated and the bond energy of the molecule was analyzed.Under the condition of microwave power 600 W at 150℃ for 4.5 h with added concentrated hydrochloric acid solution, the cyanogens group was successfully removed from ricinine molecule.The decrease in insecticidal effect of ricinine after modification indicated that the cyanogens group played an important role in insecticidal effect of ricinine.
