Richard Tudor and Michael Ashley (Davy Process Technology Ltd, London, U.K.) describe some of the improvements made to the LP OxoSM Process for the hydroformylation of propene after the early plants started operation, and the use of the process in non-propylene applications. Part I, published in the July 2007 issue of Platinum Metals Review, described the initial research and development for the process, and its commercialisation.q{ EB&Aw

Working Characteristics of Pure Platinum$`#a

!Q:^ak1u&Sdq
While there are advantages in using nominally pure platinum for industrial fabrication, its low strength may be a necessary trade-off. Yu. N. Loginov (Ural State Technical University, Ekaterinburg, Russia), A. V. Yermakov, L. G. Grohovskaya and G. I. Studenok (The Ekaterinburg Non-Ferrous Metals Processing Plant JSC, Ekaterinburg, Russia) present work on the rheological characteristics of 99.93 wt.% platinum, including its deformation resistance, aimed at optimising the technical parameters for the thermal and mechanical processing of platinum.%f?I9k Z

Cornish2,3,4 (1University of Leeds, U.K.; 2Mintek; 3DST/NRF Centre of Excellence in Strong Materials; 4University of the Witwatersrand, South Africa) continue their report on a collaborative project to build up a platinum-aluminium-chromium-ruthenium (Pt-Al-Cr-Ru) database, for the prediction of phase diagrams for alloy development. Part I appeared in the July 2007 issue of Platinum Metals Review. This paper (Part II) addresses the Pt-Cr-Ru system using new models appropriate to sparse data, with encouraging results. Part III will appear in a future issue of this Journal.r r w WZ*Z|8u

The second Novel Chiral Chemistries Japan (NCCJ) Conference and Exhibition was held in Tokyo from 16th to 17th April 2007. David J. Ager (DSM, Raleigh, U.S.A.) reviews the event, reporting an emphasis on the need to develop both more efficient asymmetric catalysts and the means to identify them. The wide variety of topics and applications discussed demonstrates that use of the platinum group metals (pgms) continues to provide new and useful methodologies to prepare fine chemicals on an industrial scale.

A recent special issue of Coordination Chemistry Reviews was entitled: “Recent Developments in the Organometallic Chemistry of N-Heterocyclic Carbenes”. Guest Editor Robert H. Crabtree (Yale University, U.S.A.) has provided a summary of the issue. NHCs are significant as spectator ligands in having both steric and electronic tunability, and the capability to promote many useful catalytic reactions, chiefly as their pgm complexes.

Thomas Ilkenhans (Johnson Matthey Technology Centre, Sonning Common, U.K.) attended the 40th Conference ‘Deutscher Katalytiker’ in Weimar, Germany, from 14th to 16th March 2007. This selective review covers the design of catalysts for molecular and supramolecular chemistry, synthesis of metal nanoparticles, preparation and application of supported pgm catalysts, and homogeneous palladium-catalysed reactions.7q r"H)`+y J#r

Robin B. Bedford (School of Chemistry, University of Bristol, U.K.), reviews the book “Metal-catalysis in Industrial Organic Processes”, edited by G. P. Chiusoli and P. M. Maitlis. Industrially significant examples of catalysis are covered, from large-scale commercial applications to fine chemicals and pharmaceutical intermediate synthesis, including pgm-catalysed processes.

The 21st annual Santa Fe Symposium® on Jewelry Manufacturing Technology was held in Albuquerque, New Mexico, U.S.A., from 20th to 23rd May 2007. Christopher W. Corti (COReGOLD Technology Consultancy, Reading, U.K.) reports that the presentations relating to palladium as a jewellery alloy provide a firm technical underpinning for this application. Further presentations on the technology of platinum jewellery manufacture added to the already substantial knowledge base for this metal.

Kim Chandler1, Ann Keep1, Sue Ellis2 and Sarah Ball2 (1Johnson Matthey, Royston, U.K.; 2Johnson Matthey Technology Centre, Sonning Common, U.K.) review a selection of chapters from the book: “Combinatorial and High-Throughput Discovery and Optimization of Catalysts and Materials”, edited by Radislav A. Potyrailo and Wilhelm F. Maier. Applications covered include gas-sensitive field-effect devices, catalyst development for hydrogen generation and for the carbonylation of phenol, and fuel cell electrocatalyst technology.
