Ethylene dimerization to 1-butene
WebThe Ethylene Dimerization process dimerizes ethylene to produce butene-2 and butene-1. The catalyst is formulated to offer a high selectivity to butene-2. The butene-2 to butene-1 product ratio is about nine to one. As such it is ideally suited to applications where ethylene is dimerized as feed to an Olefins Conversion Unit thereby permitting ... WebAlphabutol process for the dimerization of ethylene to 1-butene.2 This process was developed from Ziegler and Martin’s initial discovery that combinations of triethylaluminum and titanium or zirconium alkoxides readily convert ethylene to 1-butene with high selectivity.8 Asimilarcatalystsystem, Ti(OAr) 4/AlEt 3, was also employed to develop ...
