摘要
通过图像颗粒分析仪及恒温箱分析晶型,筛选出熔点高的吡唑醚菌酯原药。使用流点法、正交实验确定25%吡唑醚菌酯水悬浮剂的最优配方,配方组成为吡唑醚菌酯25%,THB1 2%, THB 4%,乙二醇5%,黄原胶0. 15%, AF-9903 0. 3%,水补至100%。
Pyraclostrobin TC with high melting point was screened out through the analysis of crystal form by image particle analyzer and incubator,The optimum formulation of 25% pyraclostrobin-SC was determined by flow point method and orthogonal experiment. The formulation consisted of pyraclostrobin 25%,THB1 2%,THB 4%,ethylene glycol 5%,xanthan gum 0. 15%,AF-99030. 3% and water adding to 100%.
