湿法磷酸复盐复分解生产精细磷酸钾盐反应动力学研究

摘要

Reaction kinetics of manufacturing potassium pho sphate by double decom position with potassium chloride and wet-process phosphoric acid purified by cr ystallization of melamine were studied.Key factors which influenced on reaction rate were analyzed.The control step of reaction was determined, the kinetic mod el was obtained.%研究了三聚氰胺结晶法净化湿法磷酸生产精细磷酸钾盐过程中磷酸三聚氰胺与氯化钾反应的动力学特征，分析了影响反应速度的主要因素，确定了过程的控制步骤，并得到了反应过程的动力学方程。
