ETUDE DE LA DIMERISATION DU PROPYLENE CATALYSEE EN PHASE HOMOGENE PAR DES ESPECES DU TYPE "HCoLx"

Article abstract of DOI:10.1016/S0022-328X(00)98619-4

The dimerisation of propylene in methylpentenes (60percent) at 25 deg C is catalysed by two active cobalt species.The first, HCoL3, issued from the system "Co(Acac)3/HAlEt2/L" in the presence of 1,5-cyclooctadiene, is more active (*30) and selective in 2-methyl-1-pentene (85percent of dimers) than the second, formed from HCo(COD)2.Under low pressures of propylene (3 bar), the fraction of higher oligomers (mainly trimers) increases only up to 40percent.
