苯酚羟基化合成苯二酚的热力学分析

Thermodynamic Analysis of Reaction for Synthesis of Diphenols by the Hydroxylation of Phenol

计算了以水为溶剂,过氧化氢氧化苯酚羟基化合成苯二酚的反应体系的反应焓变、吉布斯自由能变和反应的平衡常数。结果表明,生成邻苯二酚、对苯二酚的反应均为放热反应;反应在298K-368K范围内是热力学上可自发进行的反应;反应的平衡常数很大,理论上反应的平衡转化率很大。

Based on the thermodynamic datas from chemistry or engineer handbooks, the thermodynamic datas on synthesis reaction of Diphenols in water by the Hydroxylation of Phenol, including reaction enthalpy, the Gibbs free energy, and the standard equilibrium constant were calculated. The results show that the synthesis reaction is exothermic, thermodynamically feasible and has higher equilibrium transformation rate from 298 K to 368 K.
