ABSTRACT:
A single-stage reactor in the form of two concentric tubes and, one acting as a central stack and the other as a wall of reactor, widening out towards the top; a gas diffuser at the bottom of the stack, enabling gas to be injected into the liquid column above the diffuser, while a vesicle remover is located in the upper part of reactor; pipes and for feeding in the reagents, and a pipe for forcing back the gaseous phase at the top of reactor; a connection inclined by over 45.degree. to an extension of the horizontal and establishing direct communication between the bottom of reactor and a decanting chamber; and a vertical degassing tube located between connection and decanting chamber.
Application of this arrangement to the reaction between finely divided aluminum, hydrogen and at least one olefin having 2 to 30 carbon atoms, at a temperature of from 100.degree. to 200.degree. and a pressure of 30 to 200 bars, in a perfectly homogeneous medium for the preparation of alkylaluminums.
