摘要: 对乙酸和丁醇酯化反应精馏进行了实验研究和数学模拟.以Hayden-O’Connell公式和“化学理论”计算逸度系数,以NRTL方程计算活度系数,从而为模拟过程提供了较为准确的热力学数据,数学模型采用松弛法求解,计算结果和实验结果吻合良好.

Abstract: Distillation with esterification of butanol and acetic acid was studied experimentally and then followed by mathematical simulation.To provide data for the complex quaternary system,the fugacity coefficients were calculated by Hayden─OConnell equation,and the activity coefficients by the NRTL equation.The mathematical model,solved by the relaxation method,agreed well with experiments.
