Process for the separation of styrene from ethylbenzene |
| abstract |
WHEREIN R AND R'' ARE AROMATIC OR ALIPHATIC. EXEMPLARY OF THE POLYAMIDES ARE NYLON-6 AND NYLON 6, 10. -(NH-R-NH-CO-R-CO)A- AND -(NH-R-CO)A- STYRENE IS SEPARATED FROM ORGANIC MIXTURE COMPRISING STYRENE AND ETHYLBENZENE BY CONTACTING THE SAID MIXTURE UNDER PERVAPORATION PERMEATION CONDITIONS AGAINST ONE SIDE OF A POLYAMIDE PERMEATION MEMBRANE AND WITHDRAWING ON THE OTHER SIDE OF THE MEMBRANE A VAPOROUS MIXTURE HAVING AN INCREASED CONCENTRATION OF STYRENE. THE POLYAMIDES HAVE UNITS SELECTED FROM THE GROUP CONSISTING OF |
