本文从选择性分子间引力讨论介质对丙酮碘化反应速度的影响,预测丙酮浓溶液(丙酮本身亦是介质)的碘化比速度,其数值应随丙酮浓度的增加而变大 ,实验结果证明了理论的预测.丙酮浓溶液的碘化是一个较复杂的可逆反应,本研究用一简便的近似处理方法,获得一个动力学积分公式,其中〔I_2〕~*为反应达到平衡时I_2的浓度,t为时间,c为ln〔H~+〕/{〔I_2〕-〔I_2〕~*}~(k_(-2)/k_3)=kt+c,常数,k_(-2),k_3为一些步骤的比速度. 所求得的积分式关连实验数据,尚称满意. 所得比速度k与溴化反应比较,两者甚为接近,表明理论探讨的合理性
In this paper, we discuss the influence of medium on the reaction rate of acetone iodination from selective intermolecular attraction and predict the iodination rate of acetone-rich solution (acetone itself is medium), the value of which should increase with the increase of acetone concentration. The theory of prediction.Individual acetone concentration is a more complex reversible reaction, the study using a simple approximate approach to obtain a kinetic integral formula, where [I_2] ~ * for the reaction to reach a balance of I_2 concentration , t is the time, c is ln [H ~ +] / {[I_2] - [I_2] ~ *} ~ k_ (-2) / k_3) = kt + c and the constants k 2 and k 3 are Some steps of the ratio of the speed obtained by the integral correlation experimental data, is still satisfied with the obtained ratio k and bromination reaction rate comparison, the two are very close, indicating the rationality of the theoretical discussion
