    摘要： This invention provides for the separation of an amine composition undergoing processing at high temperatures and pressures which amine composition contains volatile components and less volatile components where the volatile components are desirable for further processing and/or utilization and the less volatile components are less desirable for further processing and/or utilization. The separation serves to divide the amine composition into two streams, one which is enriched in the volatile components and the other which is enriched in the less volatile components.

    摘要： A regeneration process for re-activating an ionic liquid catalyst, which is useful in a variety of reactions, especially alkylation reactions, and which has been deactivated by conjunct polymers. The process includes a reaction step and a solvent extraction step. The process comprises (a) providing the ionic liquid catalyst, wherein at least a portion of the ionic liquid catalyst is bound to conjunct polymers; and (b) reacting the ionic liquid catalyst with aluminum metal to free the conjunct polymers from the ionic liquid catalyst in a stirred reactor or a fixed reactor. The conjunct polymer is then separated from the catalyst phase by solvent extraction in a stirred extraction or packed column.
