MULTISTAGE DIMERIZATION PROCESS

摘要

A process is provided for the dimerization of an isoalkene (1) wherein the isoalkene is dimerized in a first reaction zone (2) up to a conversion of not more than about 85 %, product dimer (8) is separated in a separation zone (9), and the unreacted isoalkene (10) is further dimerized in at least one subsequent reaction zone (11).
