三氟羧草醚水剂的制备方法
摘要：
本发明涉及一种三氟羧草醚水剂的制备方法。按以下工艺步骤进行：1）首先以三氟羧草醚为原料，在10℃-40℃的条件下，以杯芳烃为溶剂进行混合；2）混合均匀后，加入羧酸酯为乳化剂，搅拌均匀；3）经过过滤滤除沉淀物，制得。本发明的优点是：1）本发明以杯芳烃为溶剂，利用杯芳烃的杯状结构能形成对三氟羧草醚良好的包围，在保持三氟羧草醚水剂分散性能的同时有具备一定的集中性能，从而在应用过程中能保持农药药性的均匀性，也能保证农药药性的集中性，提高防治效果；2）本发明将三氟羧草醚加入到乳化剂中，能保证三氟羧草醚的乳化效果，提高其分散性能。
摘要（英）：

The invention relates to a preparation method of an acifluorfen water aqua. The method comprises the following steps: 1) first mixing a raw material of acifluorfen with a solvent of calixarene at the temperature of 10 DEG to 40 DEG C; 2) mixing evenly, adding an emulsifier carboxylic ester, and stirring evenly; and 3) and filtering the sediment to obtain the water aqua. The invention has the following advantages: 1) the invention uses calixarene as the solvent, the cup-shaped structure of calixarene can form good surrounding around the acifluorfen, and has certain concentration performance while maintaining dispersion properties of the acifluorfen water aqua, so as to keep the uniformity of pesticide properties in the application process, ensure the concentration of pesticide properties, and improve the control effect; and 2) acifluorfen is added to the emulsifier to guarantee the emulsifying effect of acifluorfen, and improve the dispersion performance.
