甲基嘧啶磷稳定剂的研究

Study on Pirimiphos-Methyl Stablizer

叙述了影响有机磷农药分解的原因及控制其分解的对策 ,并针对甲基嘧啶磷的结构及其性质 ,进行了稳定剂的筛选。实验结果表明 ,选用ZRQ - 10 0或NPE - 90 1为甲基嘧啶磷原药稳定剂 ,在 5 4± 2℃ / 14d贮存条件下 ,其相对分解率分别为 3 98%和 3 5 6 %

The reason of decomposition and control method of phosphrus pesticide is described in this paper.According to the structure and physical properties of pirimiphos-methyl,the stablizer is selected by experiment,the results show that ZRQ-100 or NPE-901 can be used as pirimiphos-methyl stablizer The mixture is kept at 54±2 ℃ for 14days,the decomposition rate of pirimiphos-methyl is 3 98 % or 3 56 %
