摘要：
The present invention relates to a polymeric aromatic selective membrane comprising an cross linked polyether imide membrane that comprise the reaction of a polyether amine with an dianhydride, and that may be utilized in a process for selectively separating aromatics from a hydrocarbon feedstream comprised of aromatic and aliphatic hydrocarbons and at least one alcohol, typically ethanol.
