摘要
测定了乙酸苯酯在高温高压水中(压力15MPa,温度152～216℃)的水解反应动力学数据。结果表明在无任何外加催化剂的情况下,乙酸苯酯能够顺利进行水解反应。随温度升高,反应速率迅速增大,选择性从不足50%提高到80%以上。拟合得到反应活化能为67.77kJ/mol。
The kinetics of non-catalyzed hydrolysis of phenylacetate in water at 15MPa and temperature from 152℃ to 216℃ was investigated. The experimental results showed that no catalyst was needed for the hydrolysis reaction. With the increasing of temperature, the reaction rates increased sharply and the selectivity of phenol went up from less than 50% to over 80%. The activation energy evaluated was 67.77 kJ/mol.
