【摘要】 [方法]利用高速逆流色谱,选用不同的溶剂体系,分别对氟虫腈、氟环唑、咪草烟、氟吗啉原药中的特定杂质进行了分离提纯。[结果]在对应的溶剂体系下,分离得到的杂质纯度均超过90%。达到了杂质定性及定量分析的要求。[结论]HSCCC是一种高效的杂质分离方法。更多还原

【Abstract】 [Methods] The certain impurities of fipronil,epoxiconazole,imazethapyr,and flumorph technical were seperated in different solvent system by high-speed counter-current chromatograghy(HSCCC).[Results] It showed that the purity of each certain impurity was over 90% in the certain solvent system and satisfied the qualitative and quantitative analysis.[Conclusions] HSCCC was an efficient separation method of impurity.更多还原
