| Abstract: | This paper deals with the multivariable batch distillation techniques in the separation of fine chemicals. N-ethylaniline and N,Ndiethylaniline. The industrial production showsthat the batch distillation with hold-up, varying gas load, varying reflux and varying pressure ispracticable, and the distillation process is highly efficient and stable. The purity of the products ismore than 99%. The controlled liquid hold-up operation increases the yield. |
