September 28, 2007 - Rhodia has implemented new process technology to manufacture tetra-t-butyldiphosphinoxylene (RhodaPhos™ AL) in tonne scale quantity. RhodaPhos™ AL is typically utilised as a ligand with palladium in carbonylation reactions and has many potential applications. This highly efficient carbonylation ligand boosts turnover numbers and selectivity of reaction.

Rhodia in collaboration with Professor Martin Wills and postgraduate student Yingjian Xu of the University of Warwick have published initial results using their new XuPhos catalyst system to produce chiral alcohols. With this new, simple, system chiral purity of 99%ee can be achieved with almost complete conversion of the starting alcohol.

Rhodia’s Phosphorus & Performance Derivatives (PPD) enterprise has announced the launch of a new website to promote its line of phosphine products. As the world leader in Phosphorus chemistry, Rhodia can claim to have the world’s most extensive range of currently available phosphines, together with a fast growing portfolio of products under development.

“Rhodia has unsurpassed capabilities to provide a ‘one-stop shop’ for customers around the globe for phosphine products”, commented Mike Harrison Regional Business Director, Rhodia PPD. Our long-standing expertise in Phosphorus chemistry gives us real competitive edge in terms of manufacturing know-how, HSE and product stewardship expertise and worldwide sales support”, he added.

With considerable strengths in manufacturing technologies, Rhodia can supply phosphines in quantities from kilos up to metric tonnes, illustrated for example by our ability to produce chiral phosphines on a large scale.

From its ‘mini portal’ home page, the new phosphines site provides easy access to the full range of products available, including Binap, tri-t-butylphosphine, dppf, Chiraphos and many others.

A series of adverts in the international chemicals publication “Chemistry and Industry” as of January 2005 will support the launch of Rhodia’s Phosphines web site.

Using the strapline “One company…infinite solutions”, the adverts will underline Rhodia’s expertise in Phosphines technologies and our capacity to provide customers with the fullest range of Phosphine products – from early phase development to full manufacture. The adverts will also illustrate Rhodia’s flexible approach and aim to support customer projects from early phase development through to full manufacture.

The adverts will appear in Chemistry and Industry in January, March, May and October 2005 issues.

Rhodia’s Phosphorus and Performance Derivatives (PPD) enterprise today announced the commercial availability of the well-established ligand, BINAP.

Highly versatile, BINAP is used for a range of applications including chiral reactions, such as asymmetric hydrogenation. And with its bulky structure has potential uses in the racemic form in non-chiral applications like petrochemical processes and Palladium catalysed C-C, C-N and C-O coupling reactions. BINAP as a catalyst ligand has similar reactivity to some bulky aliphatic phosphines, however BINAP is more stable and therefore reduces the handling risks associated with pyrophoric phosphines.

Earlier this year Rhodia PPD announced it had acquired exclusive rights from Great Lakes Chemical Corporation to the Monsanto Phosphine coupling technology, allowing it to develop the processes for manufacture of various phosphine ligands, including the Nobel Prize winning BINAP.

Andreas Wilk – Market Manager for Performance Products explains, “BINAP was first discovered in 1980 by Professor Ryoji Noyori at Nogoya University, Japan. Previously expensive to buy and difficult to manufacture, the availability of all three Isomers (R, S and Racemic) at exceptional purity levels, supplied in both kilo and tonnes will be a great addition to Rhodia’s comprehensive phosphine range”

Considered a market of significant potential, Rhodia PPD continues to invest in phosphine technology and will support commercially feasible registrations where required. Rhodia is the world’s leading producer of phosphorus based speciality chemicals.
