Thermodynamic Analysis for Alkylation of Mixed Cresols with Isobutylene
摘要
Abstract
The standard molar formation enthalpies, standard molar entropies and molar heat capacities at constant pressure of the every substances in alkylation reaction process of the mixed cresols with isobutylene were calculated by means of Benson group contribution method. The vaporization enthalpies of the reactive substances at their boiling points were calculated by Trouton rule. The changes of the enthalpy, entropy, Gibbs free energy and equilibrium constant of the alkylation were obtained by Watson formula and thermodynamic relation expressions. The results indicated that the alkylations of the mixed cresols with isobutylene were exothermic. Lowering the reaction temperature was beneficial to synthesis of alkyl cresols. The alkylations are main reactions at lower reaction temperature (333 -373 K) while de-alkylations occur at high reaction temperature (over 423 K).关键词
