【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.更多还原
