Zur Oligomerisierung von 1-Decen mit ionischen Flüssigkeiten
Oligomers of higher olefins like 1-decene, known as polyalphaolefins (PAO), are used as base oils for lubricants and stand out due to a high stability combined with extraordinary greasing properties. Ionic liquids have properties that are variable in a wide range (polarity, acidity) and are …

Use of water-soluble phosphine ligands in heterogeneous hydroformylation catalysis : application to long-chain 1-alkenes
… system for the hydroformylation of 1-octene, 1-decene, and 1-dodecene to the corresponding aldehydes, has been investigated. Due to the two distinct phases - the catalytic species in the aqueous phase and the products and reactants in the organic phase - the separation of the catalyst was easily …

Incorporation of Polar Comonomers Into High Density Polyethylene With a Cyclopentadienyl-Amido Titanium Catalyst
… due to increased short chain branching. 1-TMSO-9-Decene was the most effective comonomer, as it had the highest incorporation rates (8.0 mol%) of all three of the polar comonomers. The two shorter comonomers exhibited no incorporation at all. This confirmed the hypothesis that polar comonomers …

Surface Characterization of Siloxane, Silsesquioxane, and Maleic Anhydride Containing Polymers at Air/Liquid Interfaces
… PXcMA polymers included X=1-hexene, 1-octene, 1-decene, and 1-octadecene (represented as PHcMA, POcMA, PDcMA, and PODcMA respectively). The P-A isotherms of these polymers were consistent with those obtained previously.1Tensiometry was used to determine the critical micelle concentrations …

Catalytic Light Hydrocarbon Upgrading under Methane Environment
… and upgraded under methane environment. 1-Decene is used as the model compound of heavy oil cracking distillates and reacted with methane over Ag-Ga/HZSM-5. As a consequence of methane participation, the quality of liquid product is improved in terms of higher H/C atomic ratio, higher …

Examination of Dynamic Processes in Living Ziegler-Natta Polymerization and New Polypropylene Architectures through Bimolecular Control
… and living isotactic poly(1-sup13C-decene) revealed significant differences with respect to isomerization and decomposition. Studies carried out with various isotopically labeled iso-butyl derivatives revealed isomerization concurrent with decomposition, while the only case which did …

The effects of small molecules and polymer on the phase behaviour of C16EO16 - water mixture
… a third component, oils (1-hexene, n-decane, 1-decene) or water soluble protein (lysozyme) on the lyotropic liquid crystalline phase behaviour of hexaethylene glycol n-hexadecyl ether (C16E06) and water ( 2H20) mixtures has been investigated. A combination of optical microscopy and 2H NIVIR …

Neutral and cationic complexes of the rare earth metals : synthesis, characterisation and polymerisation catalysis
… reaction with PhSiH3 or H2. Hydrosilylation of 1-decene catalysed by the in situ generated hydride complexes selectively gives 1,2-insertion into the Ln–H bond, whilst mixtures of the Markovnikov and anti-Markovnikov products are obtained in the case of styrene. The structural characterisation of …

Z-selective olefin metathesis processes and Cis/syndioselective ROMP with high oxidation state molybdenum alkylidenes
… metathesis of 1-hexene in 20% yield to 95% cis 5-decene, which represents the first report of highly Z-selective metathesis homocoupling of a terminal olefin. The decomposition of the catalyst in the presence of ethylene is explored. The syntheses of several new bulky achiral phenoxide ligands are …

Molybdenum and tungsen alkylidene species for catalytic Enantio-, Z-, and E-selective olefin metathesis reactions
… of 5000 equivalents of methyl oleate produced 1- decene (1D) and methyl-9-decenoate (M9D) with a selectivity of >99%, yields up to 95%, and a TON (turnover number) of 4750 in 15 hours. Tungstacyclobutane catalysts gave yields approximately half those of molybdenum catalysts, either at room …
