丁酸甲酯單分子解離的非諧振效應(yīng)(英文)
發(fā)布時間:2018-08-18 19:21
【摘要】:使用MP2/6-311++G(2d,2p)方法和基組,計算了丁酸甲酯單分子解離反應(yīng)體系詳細(xì)的勢能面。應(yīng)用RRKM理論,計算了在1000-5000 K的溫度范圍內(nèi)的正則系綜的速率常數(shù)。與此同時,在微正則系綜下,我們計算了溫度為1000-5000 K對應(yīng)的能量從451.92到1519.52 k J?mol~(-1)的速率常數(shù)。計算結(jié)果表明反應(yīng)通道2、4和5的非諧振效應(yīng)比較明顯。因此對于丁酸甲酯單分子解離反應(yīng)體系來說其非諧振效應(yīng)是不能忽視的。
[Abstract]:The potential energy surface of monolayer dissociation reaction system of methyl butyrate was calculated by using MP2/6-311 G (2dU 2p) method and base set. The rate constant of canonical ensemble in the temperature range of 1000-5000K is calculated by using RRKM theory. At the same time, we calculate the rate constants of the energy corresponding to the temperature of 1000-5000K from 451.92 to 1519.52 k Jnmol ~ (-1) under microcanonical ensemble. The results show that the non-resonance effects of reaction channels 2H4 and 5 are obvious. Therefore, the nonresonant effect of monolayer dissociation reaction of methyl butyrate can not be ignored.
