Method of allocation of perfluorobenzene from benzene-perfluorobenzene biasetropic mixture |
| abstract |
FIELD: chemistry. n SUBSTANCE: invention relates to a process for the isolation of perfluorobenzene biazeotropnoy perfluorobenzene benzene-benzene by chemical modification to form high boilers, which biazeotropnuyu mixture of perfluorobenzene-benzene is catalytically alkylated perfluorobenzene then isolated by distillation. Benzene content in the initial biasetropic mixture is from 5 to 75% by weight. The biasetropic mixture catalytic alkylation of benzene-olefin perfluorobenzene carried straight or branched chain with terminal or internal double bond of the general formula C n H 2n , where n = 2รท8, or mixtures thereof in the presence of a Bronsted acid or a Lewis acid alkylation catalyst. n EFFECT: hard biasetropic mixture selection from a mixture of benzene-PFB PFB desired product of high purity and substantially simplify its extraction technology. n 6 cl, 2 tbl, 10 ex |
