摘　　要：介绍了具有优良除草性能的除草剂——乙草胺新剂型微乳剂(SAA),简述了该剂型的特点.通过实验筛选出了用于配制乙草胺微乳液的乳化剂品种钙盐B、醚A及助表面活性剂正丁醇,并得出了它们的最佳配比关系∶m(醚A)∶m(钙盐B)∶m(正丁醇)=4∶1∶3.从经济的角度出发,得到了SAA和乙草胺原油之间最佳配比为m(SAA)∶m(Oil)=0.85∶0.15.同时对配出的乙草胺微乳液取样进行的性能评价表明,所配微乳液完全合格.实验表明,用此方法配制的微乳液品种分解率低、质量稳定、使用安全、社会效益显著.这种寻找SAA和乙草胺原油之间配比关系的方法,给乙草胺微乳液各组分的配比提供了全新的研究方法.A new herbicide formulations of excellent herbicidal properties-acetochlor microemulsion（SAA） was introduced and the characteristics of the new formulation outlined. The emulsifiers of forming ethylicin microemulsion have been chosen through the experiment and they are calcium salt B, ether A and assistant surfactant n-butanol. The best ratio was m （ ether A） ： m （ calcium B） ： m （n-butanol） = 4： 1： 3. In views of the economic point, the best ratio between SAA and acetochlor crude oil was m （SAA）： m （Oil） = 0.85：0.15. Experiment results showed that the prepared ethylicin microemulsion samples were completely up to quality. It is showed that the microemulsion had low resolution, stable quality, safety and outstanding society benefit. The ways of searching for best ratio between SAA and acetochlor oil provides a new research methods for the ratio of each component in the microemulsion acetochlor.
