ABSTRACT:
An apparatus for oligomerization of C.sub.4 and C.sub.5 isoolefins or the etherification thereof with C.sub.1 to C.sub.6 alcohols wherein the reactants are contacted first in a partial liquid phase reactor (boiling point reactor) with a fixed bed acid cation exchange resin catalyst at an LHSV of 5 to 20, pressure of 0 to 400 psig and temperature of 120.degree. to 300.degree. F., at a pressure to maintain the reaction mixture at its boiling point whereby at least a portion but less than all of the reaction mixture is vaporized and the entire reaction stream is directed to a catalytic distillation column reactor for further reaction of the reactants, where the improvement is having a decoupling drum between the boiling point reactor and the catalytic distillation column reactor. The addition of a decoupler drum allows the reactors to operate at a pressure independent of each other.
