20%呋虫胺可分散油悬浮剂的配方研制

Preparation of Dinotefuran 20% OD

采用湿法砂磨工艺制备20%呋虫胺可分散油悬浮剂。通过对其配方中的油相载体、乳化剂、分散剂及结构稳定剂等筛选,确定最佳配方为呋虫胺20%、OF-4816 16%、烷基酚聚氧乙烯醚2%、脂肪酸衍生物聚乙二醇酯化物1.5%、有机膨润土0.5%、结构稳定剂10#2%,大豆油补至100%。该产品流动性、稳定性好,悬浮率高,各项指标符合可分散油悬浮剂的要求。

Dinotefuran 20% OD was prepared by wet grinding technology. By screening main adjuvants such as oil carrier, emulsifier, dispersant and structure stabilizer, the optimum formula of dinotefuran 20% OD was determined as follow： dinotefuran 20%, OF-4816 16%, emulsifier alkylphenol ethoxylates 2%, dispersant 1.5%, organic bentonite 0.5%,structure stabilizer 10# 2%, soybean oil adding to 100%. Dinotefuran 20% OD had high suspension rate, good fluidity and stability. The test indexes comformed to the requirements of OD.
