醋酐合成的化学平衡计算

Calculation of chemical equilibrium for synthesis of acetic anhydride

用热力学的方法研究了醋酸甲酯及甲醇合成醋酐的反应。计算了反应温度对化学平衡常数的影响 ,温度、原料配比和压力对反应的平衡转化率和平衡组成的影响。

The reaction thermodynamics of acetic anhydride was studied.The chemical equilibrium is constant at different temperatures,and the effects of temperature,molecular ratio and pressure on equilibrium conversion ratio and equilibrium composition were calculated.It provides thermodynamic data for choosing and improving technical conditions and catalyst.
