用化学动力学方法探讨了聚乙烯吡咯烷酮碘在不同温度下(363.15K,353.15K,343.15K,333.15K)的分解规律,其有效碘浓度对分解时间的曲线为C型曲线,此曲线的变化规律可用C=G_oe~(-kt)~m回归方程表示,用此方程可求出化学动力学方程及分解反应速度方程。 The decomposition rules of polyvinylpyrrolidone iodine at different temperatures (363.15K, 353.15K, 343.15K, 333.15K) were explored by chemical kinetics. The curve of effective iodine concentration versus decomposition time was C-curve. The change of this curve The law can be used C = G_oe ~ (-kt) ~ m regression equation that can be used to calculate the chemical kinetic equation and decomposition reaction rate equation.
