separation of eight pesticides including bitertanol (1), diclobutrazol (2), fenbuconazole (3), triticonazole (4), imazalil (5), triapenthenol (6), ancymidol (7), and carfentrazone‐ethyl (8) was achieved, using normal‐phase high‐performance liquid chromatography on two cellulosed‐based chiral columns. The effects of isopropanol composition from 2% to 30% in the mobile phase and column temperature from
8种杀虫剂包括双苯三唑醇(对映体的分离1),diclobutrazol(2),腈苯唑(3),灭菌唑(4),抑霉唑(5),triapenthenol(6),嘧啶醇(7),和唑酮草酯(8)为在两个基于纤维素的手性色谱柱上使用正相高效液相色谱可实现 研究了流动相中2%至30%异丙醇组成的影响以及色谱柱温度从5至40°C的影响。对于双苯三唑醇(获得了满意的分辨率1),灭菌唑(4),抑霉唑(5),首先在(Lux Cellulose-2)和(Lux Cellulose-3)上洗脱(+)-对映体,然后先洗脱fenbuconazole(3),然后首先洗脱(-)-对映体。(+)-双氯丁唑(2)和三戊酚(6)的对映体首先在Lux Cellulose-2上洗脱。(-)-Carfentrazone-ethyl(8)首先在不完全分离的Lux Cellulose-2和Lux Cellulose-3上洗脱。获得了对氨基咪唑(7)的相反洗脱顺序。(+)‐
