A PROCESS FOR THE PURIFICATION OF DIISOPROPENYLBENZENE |
摘要 |
This invention discloses a process for the separation of diisopropenylbenzene from organic impurities in a dehydrogenation mixture comprising: (1) hydrogenating said dehydrogenation mixture to a maximum isopropenylstyrene concentration of no more than about 5% by weight in the presence of a rhodium catalyst and hydrogen to form a hydrogenated dehydrogenation mixture, followed by, (2) fractionally distilling said hydrogenated dehydrogenation mixture under conditions sufficient to separate said diisopropenylbenzene from said organic impurities in said hydrogenated dehydrogenation mixture. |
