SEPARATION OF META- AND PARA-XYLENE MIXTURE BY DISTILLATION ACCOMPANIED BY CHEMICAL REACTIONS

摘要

References(5) Cited-By(28) Mixtures of m- and p-xylene can hardly be separated by an ordinary distillation technique even if extractive distillation is used. In the present work a new method for separating the mixture is proposed. Namely p-xylene is enriched continuously by adopting a distillation accompanied by the chemical reaction of trans-alkylation on the basis of the fact that only m-xylene reacts with tert-butylbenzene. A method of computation is also presented for this new distillation process.
