摘要
采用不同有机碱用量的实验条件获得了不同晶型的啶酰菌胺,利用DSC、XRD等分析手段,对啶酰菌胺晶体进行了表征。研究了结晶时p H值对啶酰菌胺析出晶型的影响,讨论了获得啶酰菌胺的单一晶型所需的p H条件,获得了制备啶酰菌胺单一晶型的方法。
Different crystalline forms of boscalid were prepared from experiments using different amount of organic base, and were characterized using DSC, XRD and other analytical methods. The effect of pH value on crystalline forms of crystallization was also investigated, and the pH value for obtaining single crystalline form of boscalid was achieved.
