【Abstract】 For better control of potassium picrate(KP) production,the factors affected the crystallizationprocess of KP should be dissertated. On the basis of the introduction for spontaneous crystallization ofKP, orthogonal experiments are adopted to investigate the importance level of different factors in this article. The optimized technology conditions are found: feeding time 20 min,quantities of crystal modifiers 20 ml,feeding concentration 0.4 mol·1-1.更多还原
