    • A process includes periodically or continuously introducing an olefin monomer and periodically or continuously introducing a catalyst system or catalyst system components into a reaction mixture within a reaction system, oligomerizing the olefin monomer within the reaction mixture to form an oligomer product, and periodically or continuously discharging a reaction system effluent comprising the oligomer product from the reaction system. The reaction system includes a total reaction mixture volume and a heat exchanged portion of the reaction system comprising a heat exchanged reaction mixture volume and a total heat exchanged surface area providing indirect contact between the reaction mixture and a heat exchange medium. A ratio of the total heat exchanged surface area to the total reaction mixture volume within the reaction system is in a range from 0.75 in -1 to 5 in -1 , and an oligomer product discharge rate from the reaction system is between 1.0 (lb)(hr -1 )(gal -1 ) to 6.0 (lb)(hr -1 )(gal -1 ).

    • A process for the in-situ formation of an ionic liquid catalyst, in the reactor vessel intended for use in an ionic liquid-catalyzed chemical reaction, by the separate addition of the reagents needed to form the ionic liquid to the reactor for the chemical reaction. At least one reagent for such ionic liquid catalyst and at least one reagent for the desired chemical reaction can be initially added to a reactor vessel, followed thereafter by the addition of the other reagent or reagents needed to form the ionic liquid catalyst in-situ. The in-situ formation of the ionic liquid catalyst will thereby take place either before initiation of or during the desired chemical reaction (which can be an alkylation reaction of either an aromatic reagent or a paraffin or the oligomerization of an olefin). A particularly preferred chemical reaction involves the formation of a linear alkylbenzene with the initial reagent for forming the ionic liquid being aluminum trichloride and the other reagent needed to form the ionic liquid catalyst in-situ being a base (either an alkyl-containing amine hydrohalide salt or a guanidinium salt).
    • 在反应器容器中原位形成离子液体催化剂的方法,该反应器用于离子液体催化的化学反应,通过单独添加将化学反应形成离子液体所需的试剂 。 可以将至少一种用于这种离子液体催化剂的试剂和用于所需化学反应的至少一种试剂加入到反应器容器中,随后加入原位形成离子液体催化剂所需的其它试剂或试剂。 离子液体催化剂的原位形成将在所需的化学反应(其可以是芳族试剂或链烷烃的烷基化反应或烯烃的低聚)期间或期间进行。 特别优选的化学反应包括形成直链烷基苯,其中用于形成离子液体的初始试剂是三氯化铝,而原位形成离子液体催化剂所需的其它试剂是碱(含烷基胺氢卤酸盐 或胍盐)。
