ABSTRACT:
A process for the preparation of an aminoethanol is described wherein an amine is vaporized in a collection vessel and the vapors are caused to pass upwardly through a defined reaction zone into a condensation zone where they are condensed and caused to flow downwardly into the reaction zone. In the reaction zone the flow toward the collection zone is retarded and, while retarded, epoxide reactant is directed thereagainst. The aminoethanol so formed is removed into the collection zone such as by directing condensed amine thereagainst.
