摘要:采用Benson基团贡献法计算了 2 ,6 -二异丙基苯酚和 2 ,6 -二异丙基苯胺的标准生成热△H、绝对熵S和热容Cp,计算了胺化法制备 2 ,6 -二异丙基苯胺的反应自由能变化△G、平衡常数Kp 及2 ,6 -二异丙基苯酚的平衡转化率X。结果表明 :该反应为放热反应 ,其吉布斯自由能变化为负值 ,2 ,6 -二异丙基苯酚可望得到较高的平衡转化率。
The standard heat of formation △ H 0 f,entropy S 0 and heat capacity C p of 2,6-diisopropylphenol and 2,6-diisopropylaniline are calculated by the method of Benson group contribution.The free energy change of the reaction △ G ,equilibrium constant K p and equilibrium conversion X of 2,6-diisopropylphenol are evaluated according to the chemical thermodynamics principle.The results show that this reaction is exothermic,and the reaction △ G is negative,and high equilibrium conversion x of 2,6-diisopropylphenol is expectable.The data calculated may serve as the foundation for industrial production.
