Abstract Recent progress in macromolecular reaction engineering has enabled the synthesis of sequence‐controlled polymers. The advent olefin block copolymers (OBCs) via chain shuttling polymerization ethylene with α‐olefins opened new horizons for polyolefins having a dual character thermoplastics and elastomers. Nevertheless, use two catalysts different comonomer selectivities agent, dragging ...

The control on product distributions in Fischer-Tropsch synthesis by feeding olefins in the n-paraffin solvent over a 20 wt.% Co/SiO2 catalyst under the typical reaction conditions of 503K, 2.1MPa, H2/CO = 2, and co-fed olefins 16 mol% in CO base in a trickle bed reactor has been studied. The selected co-fed olefins include 1-octene, 2-octene and 1-dodecene. Results showed that the addition of ...

Abstract The selective hydrogenation of octyne in a mixed 1‐octyne/1‐octene feed was investigated by employing Pd/Al 2 O 3 and PdAg/Al catalysts coated with 1‐butyl‐3‐methylimidazolium dicyanamide ([BMIM][DCA]) as SCILLs (Solid Catalysts an Ionic Liquid Layer). All were compared to organically modified, 1‐ethylimidazole (EIM) catalyst determine if there is SCILL effect. Results the catalysis sh...

The isolation and characterization of a strain of Pseudomonas oleovorans which epoxidates 1-octene at a rate nine times that of the original strain are described. In addition, it has been confirmed that a greater amount of the mono-epoxide product is formed from 1,7-octadiene than is formed from 1-octene. 1,7-octadiene will not support growth, but will induce the enzymes required for epoxidation.

Biphasic hydroformylation of 1-octene was performed using rhodium sulfoxantphos catalyst dissolved in [BuPy][BF4] ionic liquid. Preliminary experiments proved this system to retain the catalytic complex within the ionic liquid phase and to maintain a high selectivity towards the linear aldehyde (n:iso ratio of 30) over several cycles. Process parameter investigation showed a first order depende...

Russet spotting (RS), consisting of numerous small brown spots on the midrib of head lettuce (Lactuca sativa), is a physiological disorder induced by exposure to ethylene. In leaves suffering RS, the increase in spotting was accompanied by a parallel increase in the amount of phenolic compounds. Of these, chlorogenic acid and isochlorogenic acid were identified. Ethylene induced high phenylalan...

Surface modification of nanoparticles is often utilized to tailor the interfacial properties in dielectric nanocomposites. Introducing different functional groups nanoparticles’ surface may induce localized states (traps) that can enhance performance material depending on their density and energy levels. Furthermore, filler affect dispersion quality crystallization nanocomposites which ultimate...

The insertion, elimination and isomerisation of octenes with di-n-octylaluminium hydride [HAl(Oct)2], tri-n-octylaluminium [Al(Oct)3] and sec-octylaluminium species have been studied as individual steps in a putative aluminium based contrathermodynamic olefin isomerisation process. While elimination of 1-octene from [Al(Oct)3] is energetically unfavourable, the process is driven by high tempera...
