Liquid Phase Hydrogenation of 1-Hexene and 2-Hexene with 30 Å Platinum Particles on Alumina Support.

Homo-Polymerization of 1-Hexene Catalysed by O^N^N (Salicylaldimine)Iron(III) Pre-Catalysts to Branched Poly(1-hexene)

Five new iron(III) 1-hexene polymerisation catalysts were prepared from the reactions of 2,4-di-tert-butyl-6-(2-(1H-imidazol-4-yl)ethylimino)methylphenol (L1), or 4-tert-butyl-6-(2-(1Himidazol-4-yl)ethylimino)methylphenol (L2) or 2,4-di-tert-butyl-6-[(2-pyridin-2-yl-ethylimino)methyl-phenol (L3) with anhydrous iron(II) halides to form [FeCl2(L1)] (1), [FeBr2(L1)] (2), [FeI2(L1)] (3), [FeBr2(L2)...

Hydroformylation of 1-Hexene over Rh/Nano-Oxide Catalysts

The effect of nanostructured supports on the activity of Rh catalysts was studied by comparing the catalytic performance of nanoand bulk-oxide supported Rh/ZnO, Rh/SiO2 and Rh/TiO2 systems in 1-hexene hydroformylation. The highest activity with 100% total conversion and 96% yield of aldehydes was obtained with the Rh/nano-ZnO catalyst. The Rh/nano-ZnO catalyst was found to be more stable and ac...

INFRARED STUDIES OF 1-HEXENE ADSORBED ONTO Cr3+-EXCHANGED MONTMORILLONITE

-When 1-hexene was adsorbed by Cr3+-montmorillonite at room temperature, all evidence of C=C(str) vibrations was lost. Protonation of the alkene occurred, and the secondary carbocation formed was bound at a site on the primary coordination sphere of the interlayer cation. Some of the hydrogen atoms of these primary-sphere water molecules were involved in strong hydrogen bonds to the silicate sh...

Photolysis of cis-Hexene-2 and cis-Butene-2 at 2026 and 2062 A

Interplay of reversible chain transfer and comonomer incorporation reactions in coordination copolymerization of ethylene/1–hexene

Coordinative chain transfer polymerization (CCTP) has opened a new path for the development of novel products like olefin block copolymers and chain-end functional polyolefins. However, conflicting results are frequently reported on the catalyst performance including activity and comonomer selectivity under CCTP conditions. Here we have selected two catalysts including rac-ethylenebis(1-η5-inde...
