Rationalisation of solvent effects in the diels-alder reaction between cyclopentadiene and methyl acrylate in room temperature ionic liquids

Paul Joseph Dyson, Gabor Laurenczy, Ana Vidis

The Diels-Alder reaction between cyclopentadiene and methyl acrylate in ionic liquids has been studied in detail. The effect of contamination of the ionic liquids by common impurities, viz. sodium and chloride ions, and water, on the selectivity has been i ...

Heterobimetallic complexes as catalyst precursors for the Oppenauer-type oxidation of alcohols

Kay Severin, Sébastien Gauthier

A heterobimetallic Ru(II)-Rh(I) complex has been identified as a potent catalyst precursor for the Oppenauer-type oxidation of alcohols. With 0.1-0.5 mol% of this complex and K2CO3 as the co-catalyst, it is possible to oxidize secondary and primary alcohol ...

A heterobimetallic rhodium(I)-ruthenium(II) catalyst for the Oppenauer-type oxidation of primary and secondary alcohols under mild conditions

Kay Severin, Sébastien Gauthier

A heterobimetallic complex, in which a RuCl2(acetone) (PPh3)(2) fragment is connected via three chloro bridges to a (eta(4)-C4Ph4CO)RhCl fragment, has been identified as a potent catalyst precursor for the Oppenauer-type oxidation of alcohols. With 0.1-0.5 ...

Acrylic acid grafting and collagen immobilization on poly(ethylene terephthalate) surfaces for adherence and growth of human bladder smooth muscle cells

Florian Maria Wurm, Peter Frey

In tissue engineering, degradable or non-degradable polymer matrices can act as cell-carrier-scaffolds. Cell adhesion and growth on these scaffolds can be promoted by immobilizing extracellular matrix proteins. Therefore, in this study, polymer poly(ethyle ...

Human urothelial cells grown on collagen adsorbed to surface-modified polymers

Florian Maria Wurm, Peter Frey

OBJECTIVES: Tissue engineering methods can be applied to regenerate diseased, or congenitally missing, urinary tract tissues. Urinary tract tissue cell cultures must be established in vitro and adequate matrices, acting as cell carriers, must be developed. ...

Membrane reactor microstructured by filamentous catalyst

Albert Renken, Lioubov Kiwi, Olivier Wolfrath

A novel design of microstructured membrane reactor with micro-channels formed between closely packed catalytic filaments is reported. The system comprises filaments of 7 mm in diam. and has a laminar flow with a short radial diffusion time. This leads to l ...

Modeling of a Buss-Kneader as a polymerization reactor for acrylates. Part 1: Model validation

Albert Renken

The Buss-Kneader is generally known as a compounding device. Although a reasonable number of papers have been published on extruders as polymerization reactors, only little is known about the behavior of the Buss-Kneader when used as a polymerization react ...
