Piperazine-Containing Polymer Brush Layer as Supported Base Catalyst in a Glass Microreactor
The covalent attachment of piperazine onto the inner walls of a microreactor using glycidyl methacrylate polymer brushes has been demonstrated. The piperazine-containing polymer brushes were first grown on a flat silicon oxide surface and were characterized by contact angle, Fourier transform infrared (FT-IR), ellipsometry, and X-ray photoelectron spectroscopy (XPS). The applicability of the ca...
متن کاملGallium-containing polymer brush film as efficient supported Lewis acid catalyst in a glass microreactor
Polystyrene sulfonate polymer brushes, grown on the interior of the microchannels in a microreactor, have been used for the anchoring of gallium as a Lewis acid catalyst. Initially, gallium-containing polymer brushes were grown on a flat silicon oxide surface and were characterized by FTIR, ellipsometry, and X-ray photoelectron spectroscopy (XPS). XPS revealed the presence of one gallium per 2-...
متن کاملHeterogeneous catalysis inside a microreactor containing acid-functionalized polymer brushes
Microreactor technology represents a new and promising approach to carry out analytical and organic chemistry. 1 This is mainly due to the numerous advantages, especially in terms of increased surfaceto-volume ratio as a result of the downsizing of the dimensions (order of microns). This allows a better and faster mixing between the components of a reaction. The small dimensions created within ...
متن کاملBiodiesel production from soybean oil using ionic liquid as a catalyst in a microreactor
In the present study, Choline hydroxide (ChOH) as an ionic liquid catalyst was used for transesterification of soybean oil into biodiesel in a microchannel reactor. The effects of three variables i.e. reaction temperature, catalyst dosage and total flow rate on fatty acid methyl ester (FAME) content (wt. %) were optimized using Box–Behnken experimental design. In order to predict the FAME conte...
متن کاملEfficient Polymer-Supported Sharpless Alkene Epoxidation Catalyst*
Homogeneous linear poly(tartrate ester) ligands provide high chemical yields and enantiomeric excesses in the epoxidation of trans-hex-2-en-1-ol using Ti(OPr)4-tert-butyl hydroperoxide. Branched poly(tartrate ester) can be use as heterogeneous ligands in the epoxidation of trans-hex-2-en-1-ol using Ti(OPr)4-tert-butyl hydroperoxide. Removal and recovery of the polymer catalyst is a simple filtr...
