Determination and Simulation of the Equilibrium Data in the Production of Mesitylene Using the Method of Exactive Distillation
【摘要】 以邻苯二甲酸二丁酯(DBP)为萃取精馏溶剂,测定了邻甲乙苯—均三甲苯—偏三甲苯体系的二元及三元汽液平衡数据;编程关联了W ilson模型参数;采用物料平衡三对角矩阵法对萃取精馏过程进行了模拟,得出了萃取精馏塔的最佳操作条件,为萃取精馏法生产均三甲苯提供了基础数据。
【Abstract】 The binary and ternary experimental equilibrium data of the composites of mesitylene,1-methyl-2-ethylbenzene and 1,2,4-trimethylbenzene and the infinite activity coefficients γ~∞ are measured in the solvent of DBP.After correlating parameters in the model of Wilson,using the method of tri-diagonal matrix in material balance,the process of extra-distillation is simulated and the optimized operation parameters are obtained,which provide the basic data for the industrial production of mesitylene.
