| Abstract: | 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. |
