摘要
[目的]为了提高药效,同时减少对环境的污染,设计了5%啶虫脒乳油的不同配方。[方法]通过冷贮、热贮、外观比较、酸碱度测定等方法测试了溶剂的溶解性和乳化剂的乳化效果。[结果]混苯作溶剂;乳化剂3.2%103、2.7%107、1.5%农乳500比例下得到的药剂溶解性好,稳定性较强;冷贮后pH值稳定而且啶虫脒析出率为0.36%,热贮后pH值稳定,没有絮状物出现,啶虫脒分解率为1.84%。[结论]5%啶虫脒乳油配方为:3%二甲基甲酰胺作助溶剂,由3.2%103、2.7%107、1.5%农乳500混合作乳化剂,混苯作溶剂补齐100%。
[Objective] The present study aims to look for the perfect formula of 5% acetamiprid EC based on the several formulas. [Methods] Solubility
of solvents and the emulsification of emulsifier were measured. [Results] when the pesticides were dissolved with mix Benzene and were emulsified by
3.2% 103, 2.7% 107 and 1.5% Nongru 500 emulsifier, the pesticides were looked very well and the pesticides also showed a higher stability .1he low or high temperature had no effect on the pH value and the content of 5% acetamiprid EC [Conclusion] The determined fonnula of 5% Acetamiprid EC were that：5% Acetamiprid,3.2% 103,2.7% 107,1.5% Nongru 500, mix Benzene olvent to fill.
