Authors: Kant M. , Martin A. , Giuffrida G. , Rosano S.
Published: July 2006

Aus industrieller Sicht ist die Hydroformylierung interner Olefine zu terminalen Aldehyden besonders interessant, da Mischungen interner Olefine deutlich billiger sind als das terminale Olefin. Hieraus rührt ein besonderes Interesse an der Entwicklung neuer Katalysatoren, die interne Olefine im wässrigen Zweiphasensystem hydroformylieren können.

Neue Prozessoptionen für die Nutzung von Zeolithen in überkritischen Fluiden und ionischen Flüssigkeiten
Authors: Gläser R.
Published: July 2006

Überkritische Fluide und ionische Flüssigkeiten bieten interessante Optionen für die Modifikation und Nutzung von Zeolithen als Adsorbenzien und Katalysatoren. Nach einer kurzen Beschreibung der wichtigsten Eigenschaften dieser Lösungsmittel werden Beispiele für Anwendungen von Zeolithen in überkritischen Fluiden und ionischen Flüssigkeiten aus der aktuellen Literatur besprochen. Dabei wird im Besonderen auf den Einfluss der Reaktionsmedien auf die Vorgänge im Inneren von Zeolithporen eingegangen, z. B. bei formselektiven Umsetzungen an Zeolithkatalysatoren. Aus den behandelten Beispielen werden das Potenzial und die zukünftigen Herausforderungen für die Nutzung von Zeolithen in überkritischen Fluiden und ionischen Flüssigkeiten abgeleitet. Besonders attraktive Prozessoptionen ergeben sich aus einer kombinierten Anwendung von sowohl ionischen Flüssigkeiten als auch überkritischen Fluiden.
Der isotherme Labor‐Festbettreaktor mit quantitativer schneller Online‐Analytik als vielseitiges Instrument in der Redoxkatalyse
Authors: Aßmann J. , Muhler M.
Published: July 2006

Der isotherme Festbettreaktor mit quantitativer schneller Online‐Analytik ermöglicht einerseits eine schnelle wissensbasierte Optimierung der Katalysatorsynthese bei Gasphasenprozessen. Andererseits lassen sich durch die enge Kopplung von stationären und transienten kinetischen Experimenten in diesem Reaktor vertiefte Einblicke in die Mechanismen der Redoxkatalyse gewinnen. Durch die Verknüpfung mit Befunden aus schwingungsspektroskopischen In‐situ‐Experimenten kann daraus eine rationale Katalysatoroptimierung resultieren. Der Übersichtsbeitrag erläutert die Umsetzung dieses Konzepts am Lehrstuhl für Technische Chemie der Ruhr‐Universität Bochum anhand der chemischen Gasphasensynthese von Kohlenstoff‐Fasern, der oxidativen Aminierung von Benzol zu Anilin und der CO‐Oxidation mit RuO2.

Can the Clusters Zr6O4(OH)4(OOCR)12 and [Zr6O4(OH)4(OOCR)12]2 Be Converted into Each Other?
Authors: Puchberger Michael , Kogler Franz René , Jupa Myhedin , Gross Silvia , Fric Helmut , Kickelbick Guido , Schubert Ulrich
Published: July 2006

Upon reaction of zirconium alkoxides, Zr(OR)4, with carboxylic acids, the clusters Zr6O4(OH)4(OOCR)12 (Zr6) or [Zr6O4(OH)4(OOCR)12]2 (Zr12) were obtained, depending on the employed carboxylic acid. The structures of Zr12 clusters with acetate, propionate, vinyl acetate or 3,3′‐dimethylacrylate ligands were determined by single‐crystal X‐ray diffraction, as well as that of methacrylate/acetate and methacrylate/propionate mixed‐ligand clusters. The structure of the hafnium cluster [Hf6O4(OH)4(acetate)12]2 is also reported for comparison. The Zr12 clusters are structurally related to the Zr6 clusters since they are composed of two Zr6 sub‐units which are bridged by four carboxylate ligands. In each compound, carboxylic acid molecules interact with the cluster by hydrogen bonding to part of the μ3‐OH ligands. The clusters are highly dynamic in solution, due to site exchange of the carboxylate ligands; low‐temperature NMR spectra of the clusters correspond to the solid‐state structures. The Zr6 and Zr12 clusters can be clearly distinguished by their solution NMR spectra. Reactions between selected Zr12 clusters and carboxylic acids led to the conclusion, that only part of the ligands is accessible for ligand exchange reactions. In contrast, all ligands were exchanged when the Zr6 cluster Zr6O4(OH)4(methacrylate)12 was treated with an excess of propionic acid, and Zr6O4(OH)4(propionate)12 was formed. However, the Zr12 cluster [Zr6O4(OH)4(propionate)12]2 was obtained from the reaction of Zr(OBu)4 with propionic acid. The Zr6 and Zr12 clusters thus do not interconvert at the given reaction conditions. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Direct Asymmetric Aldol‐Tishchenko Reaction
Authors: Mlynarski Jacek
Published: July 2006

The asymmetric direct aldol reaction of nonpreactivated substrates constitutes one of the most powerful tools in current synthetic chemistry. In the last few years, chiral metal complexes have been found to catalyze the direct aldol addition of unmodified ketones to aldehydes with both high efficiency and selectivity. However, many problems have to be overcome in this still young field of chemistry. The most challenging aspect of this chemistry is the substrate limitation of known catalysts. In this field, the asymmetric aldol‐Tishchenko reaction can be regarded as a parallel methodology that expands the scope of possible applications. In the aldol‐Tishchenko reaction, two aldehyde molecules undergo addition to form an aldol adduct, which is subsequently reduced by a third aldehyde to yield 1,3‐diol monoesters through a [3,3]‐bond reorganization. With the use of aldehydes and ketones in the aldol‐Tishchenko reaction, diols with three adjacent stereogenic centers can be created in one single operation. Thus, the reaction can be regarded as an extremely atom efficient method for the construction of enantiomerically enriched products that can serve as fundamental building blocks in synthesis. Moreover, the aldol‐Tishchenko condensation is nowadays the most efficient methodology available for the direct catalytic asymmetric aldol reaction of methylene ketones. This article provides a synopsis of this field and highlights some of the challenges that still remain.(© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
Fiberboards Based on Sugarcane Bagasse Lignin and Fibers
Authors: Hoareau William , Oliveira Francielli B. , Grelier Stephane , Siegmund Bernard , Frollini Elisabete , Castellan Alain
Published: July 2006

Summary: Fiberboards were prepared using phenolic type resins (phenol‐formaldehyde) and sugarcane bagasse fibers. Lignin extracted through an organosolv process from sugarcane bagasse was used as substitute of phenol in phenolic resins from 40 (lignin‐phenol‐formaldehyde) to 100 wt.‐% (lignin‐formaldehyde) substitution. Some of the fibers were chemically modified by oxidation with chlorine dioxide and treatment with furfuryl alcohol (FA), leading to fibers coated with polyfurfuryl alcohol. Thermal analysis (DSC and TGA) of the prepolymers allowed setting up an efficient curing to prepare fiberboards. Impact strength and water absorption were measured showing the importance of the curing pressure to obtain good performance. When chemically modified fibers were used to prepare board samples, enhanced durability against white root fungi is observed, and to a less degree against brown root fungi. Sugarcane bagasse fiberboards were prepared from prepolymers where lignin substituted phenol up to 100%. This replaces these materials in advantageous position, relating to those prepared from phenol‐formaldehyde resins, due to their high content of renewable raw materials. The results obtained are promising for the utilization of sugarcane bagasse as raw materials for preparing fiberboards to be used in tropical areas.

Compatibilization of Conductive Polyethylene/Polyaniline Blends
Authors: Annala Minna , Löfgren Barbro
Published: July 2006

Summary: The compatibilization of polyethylene/polyaniline (PE/PANI) blends and the preparation of plasticized PANI/camphorsulfonic acid (CSA) complexes suitable for melt blending were studied. Rheological properties of the components essentially affected the morphology of the blend and thereby the electrical conductivity. The hydrogen bonds between the PANI complex and the functionalized metallocene PE used as compatibilizer compensated the unfavorable viscosities of the components. Mechanical properties of PE/PANI blends were improved, and electrical conductivity of the blends remained the same or increased through addition of functionalized metallocene polyethylene. Plasticized PANI/CSA complex with good electrical conductivity was successfully prepared.

Synthesis, Characterization and Properties of Novel Poly(urethane‐imide) Networks as Electrical Insulators with Improved Thermal Stability
Authors: Yeganeh Hamid , Atai Mohammad , Hojati Talemi Pejman , Jamshidi Sadegh
Published: July 2006

Summary: A new series of thermoplastic poly(urethane‐imide)s (TPUI1‐4) containing hydroxyl groups in the backbone was synthesized from the reaction of epoxy‐terminated polyurethane prepolymers (EPU1‐4) and an imide containing diacid (DIDA) chain extender under optimized reaction conditions. EPU1‐4 was prepared through end‐functionalization of NCO‐terminated polyurethanes based on polyester polyol (CAPA) and hexamethylene diisocyanate with glycidol. A blocked isocyanate (BIC) was made from the reaction of trimethylol propane (TMP), toluene diisocyanate (TDI) and N‐methylaniline (NMA). Polymer networks were prepared from the reaction of librated isocyanate groups of BIC with hydroxyl groups of TPUIs. The starting materials and polymers were characterized by conventional spectroscopic methods and the physical, thermal and electrical properties of crosslinked networks were studied. Investigation of the recorded properties for these samples showed considerable improvement in thermal and electrical properties in comparison to common polyurethanes.

Conducting Composites of Polyurethane Resin and Polypyrrole: Solvent‐Free Preparation, Electrical, and Mechanical Properties
Authors: Deligöz Hüseyin , Tieke Bernd
Published: July 2006

Summary: Three methods were used for solvent‐free preparation of conducting composites of PUR and PPy. In all cases, PUR was prepared from TDI and hydroxol 15‐W as polyol cross‐linker, whereas PPy was obtained upon oxidative coupling of Py using ferric chloride as oxidant. In method 1, PPy powder was dispersed in hydroxol. After addition of TDI the mixture was cured to yield the final product. In method 2, ferric chloride and Py were dissolved in hydroxol and a PPy dispersion was obtained. Then TDI was added and the final product was obtained upon curing. In method 3, Py was dissolved in TDI and ferric chloride dissolved in hydroxol. Then the two solutions were mixed and cured resulting in the simultaneous formation of PPy and PUR. Method 1 led to composites with a specific electrical conductivity σ of 10−10 S · cm−1 and a Shore A hardness of 40 to 55. Using methods 2 and 3, composites with σ values of 10−7 S · cm−1 and a hardness of 30 to 40 were obtained. Presence of moisture increased the σ values and decreased the hardness. Due to the solvent‐free preparation, the maximum PPy content of the samples was limited to 10 wt.‐%. The studies also demonstrated that the conductivity was mainly dependent on the amount of ferric chloride present in the sample and not on the PPy content, suggesting that the conductivity was ionic.

Quantification of Reductive Species Produced by High Voltage Electrical Discharges in Water
Authors: Sahni Mayank , Locke Bruce R.
Published: July 2006

Summary: The formation of reductive species has already been documented in various advanced oxidation–reduction processes (AORP) such as ultrasound and radiation processes. Reductive species are important in degrading mixed aqueous wastes and nitro‐ and chloro‐contaminants to achieve higher degradation efficiencies than can be attained by the reaction of contaminants with hydroxyl radicals (the primary reactive species produced by all AORP). The present study quantifies the total amount of reductive species produced by aqueous phase high voltage pulsed electrical discharge, using chemical probes tetranitromethane and nitroblue tetrazolium chloride. The effects of various electrical, physical, and chemical parameters on the generation of reductive species are investigated.
