【摘要】 有机化学反应中,反应物常常同时平行地进行不同的反应,温度不仅影响反应速率,而且由于温度对主反应及副反应的影响是相同的,即升高温度,在加快主反应速率的同时也加快了副反应的速率。但温度对主副反应的影响程度不同,文章根据Arrhenius公式,探讨温度和指前因子对反应速率的影响及其程度,提出了反转温度Tc这个概念。更多还原

【Abstract】 In organic synthesis, side reactions occur usually at the same time as the actual main reaction, in which, the reaction temperature has the same impacts on both the main and side reactions. That is, both the main and side reactions can be accelerated by an increase in temperature. However, the ratio between competing reactions may be influenced by a change in temperature because their activation energies and pre-exponential factors are different in most cases. Therefore, we investigate the effect of the reaction temperature on the reaction rates, and advance the reverse temperature Tc.更多还原
