A new way was introduced to synthesize spherical crystal of potassium 4,6-dinitrobenzofuroxanate (KDNBF). Crystal modifiers, such as PVA, Tween 80, Span, Na-CMC, Dextrin and Triton X were used to control the shape of KDNBF. Of all the crystal modifiers, Tween 80 behaved most satisfying. The product was characterized by using FT-IR, DSC and elemental analysis techniques.%介绍了一种制备球形KDNBF的新方法.通过使用PVA、吐温80、司盘、NaCMC、糊精、Triton X等表面活性剂,可以控制KDNBF的结晶形状,在这些表面活性剂中,吐温80的效果最好.制备出的KDNBF用FT-IR、DSC和元素分析等方法进行了表征.
