摘要
由对羟基苯甲酸与丙醇制备对羟基苯甲酸丙酯为一复合反应体系。用基团贡献法计算了该反应体系的标准气相生成焓、气相绝对熵、理想气体热容、气化热等基础热力学数据;并在此基础上,绘出了反应平衡常数随温度变化的曲线。热力学分析结果对实验室研究及工业化生产有一定的指导意义。
The synthesis of propyl p - hydroxybenzoate from p - hydroxybenzoic acid and propanol is a complex reaction system. The standard heat of formation, standard entropies, heat capacity and vapour heat of each subtance were calculated by methods of Benson - group contribution. The curve of equilibrium constant vs temperature was obtained. It was very important for experimental research and scale up of the process.
