Abstract: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. |
Key words:boscalid; crystalline form I; crystalline form II; the value of pH |
