Study on the Inclusion Action of Hydroxypropyl-β-cyclodextrin and Cyhalothrin
摘要
Abstract
[Objective]The aim was to study the inclusion action of hydroxypropyl-β-cyclodextrin and cyhalothrin so as to lay a foundation for utilizing synthetic pyrethroid insecticides better. [Method]The inclusion complex of hydroxypropyl-β-cyclodextrin and cyhalothrin was prepared by liquid-phase method and it was characterized by infrared spectrometry and microscopic observation. [Result]It was shown on the infrared spectrogram of cyhalothrin that the absorption peak of stretching vibration of C-H bond in benzene ring was at 3 070.08 cm-1, the absorption peaks of stretching vibration of C=O double-bond in ester bond and C=C double-bond in benzene ring were at 1 723.95, 1 585.80, 1 585.80, 1 492.84 and 1 447.38 cm-1 and the absorption peaks of substituted benzene were at 1 009.24、960.30、813.56、756.84 and 697.04 cm-1. It was shown on the infrared spectrogram of inclusion complex of hydroxypropyl-β-cyclodextrin and cyhalothrin that the absorption peak of CD-hydroxyl was at 3 400.06 cm-1, the absorption peak of C-H bond in benzene ring of cyhalothrin was at 2 930.33 cm-1 and the absorption peak of C=O double-bond in ester bond was at 1 724.18 cm-1. It was found through microscopic observation that the background of methylene blue glass with inclusion complex in solution was blue and the even and remote transparent circular points dispersed in the center were the aggregates of inclusion complexes. [Conclusion]The inclusion complex could be made from cyhalothrin and hydroxypropyl-β-cyclodextrin and it could be made into pesticide formulation with water as substrate.关键词
