5-diisopropyl-4-methylbenzene (V) and (IV). The interaction of (IV) with 1-chloro-4-methylbenzene (VI) with the formation of (I) and (II) has also been studied. These experiments have been performed for the compounds in the liquid state between 303 and 403 K. From the values of the equilibrium constants the following pairs of results have been calculated for Δ r H m o /(kJ·mol −1 ) and Δ r S m o /(J·K
摘要 研究了 1-氯-3-异丙基-4-甲基苯 (I) 和 1-氯-2-异丙基-4-甲基苯、1-氯-2,6-二异丙基-4-甲基苯 (III) 之间的异构化平衡。 )和1-氯-2,5-二异丙基-4-甲基苯(IV),以及1-氯-3,5-二异丙基-4-甲基苯(V)和(IV)之间。还研究了 (IV) 与 1-氯-4-甲基苯 (VI) 与 (I) 和 (II) 形成的相互作用。这些实验是针对 303 到 403 K 之间的液态化合物进行的。根据平衡常数的值,已经计算出以下对 Δ r H mo /(kJ·mol -1 ) 和 Δ r S 的结果mo /(J·K -1 ·mol -1 ): I = II, -(3.12 ± 1.08) 和 (4.04 ± 3.18); III = IV, (0.43 ± 0.17) 和 (2.68 ± 0.25);V = IV,-(10.08 ± 4.86) 和 (5.40
