摘要
以α—三唑基频那酮和2,4—二氯苯甲醛为原料,按缩合、转位等工艺路线来制备烯唑酮,所制备的烯唑酮的缩合反应收率可达93%.对烯唑酮顺反异构体的分离进行了实验研究,根据烯酮Z—COCl2(烯酮的反式结构)和E—COCl2(烯酮的顺式结构)的溶解度差异来进行顺反异构体的分离,已初步成功分离出烯唑醇中间体烯唑酮的顺反异构体,该分离方法目前处于改进阶段.
This synthesis process of diniconazole is carried out in the two steps of condensing, using α-triazolylpinacolone and 2,4-dichlorobenzaldehyde for material shitting and reducing. The production rate of condensation reaction is about 93%. This paper investigates the separating of the Z-COCl2 and E-COCl2 according to their differences of their solubilities and succeeds in isolating maleic and reverse diniconazole＇s intermediate ofthiazole ketone.The way of separating needs to be improved.
