Rhodia company

Thus, the Rhodia company developed and applied an industrial process for fhe acylation of anisole with acetic anhydride over BEA zeolite to selectively give para-acetylanisole. Furthermore, the reaction of isobutyl-benzene with the same acylating agent leads with high yield and selectivity to para-acetyl isobutylbenzene, which is an intermediate in the synthesis of ibuprofen, an important anti-inflammatory drug. ... 

In recent months, three nylon producers (DMS, DuPont, and Honeywell) have developed closed-loop recycling processes for nylon carpet,15 thereby joining companies like BASF, Allied, and Rhodia, which have been recycling nylon on a modest level for years. DuPont is building a demonstration plant in Maitland, Ontario, which will be dedicated to the chemical recycling of nylon-6,6 and nylon-6. The newly developed ammonolysis process invented by DuPont can be used to depolymerize both nylon-6 and nylon-6,6. However, the cost of recycled nylon is estimated to exceed that of virgin nylon by ca. 25%.

Most of today s best-known hne-chemical companies, such as Cambrex, Clariant, Degussa, Dowpharma, DSM, and Rhodia (see Table 2.2), are subject to the abovementioned characteristics. Customers prefer to do business with midsize companies, because communications are easier (they typically deal directly with the decisionmaker)—and they can better leverage their purchasing power. Lonza s custom manufacturing business, apart from biotech, is still mainly concentrated on the original Visp, Switzerland site in terms of production and R D, and therefore has conserved a number of advantages that are typical of midsize companies. 

In a keynote address delivered at Informex 2003, Andrew Liveris, now CEO of Dow Chemical, presented a list of seven companies that would still be top players in 2006, namely, Akzo Nobei/Diosynth, Avecia, BASF, Degussa, DSM, Dowpharma, and Lonza. Implicitly, he predicted that Bayer, Boehringer-Ingelheim, Cambrex, Clariant, and Rhodia Chirex would fail behind. The underlying metrics for the classification were not given [2]. 

A third catalytic system was proposed more recently and based on vanadium aluminum oxynitrides (VALON) [30]. The maximum acrylonitrile yield reported was about 30%, but with acrylonitrile productivity four times higher than for V/ Sb/W/Al/O catalysts and one order of magnitude than for Mo/V/Nb/Te/O. Other companies have studied and developed proprietary formulations but, in general, catalytic systems belong either to the antimonates family (Rhodia, BASF, Nitto, Monsanto) [31-33] orto the molybdates family. 

One widely used solution was the creation of new chemical entities through various spinoffs. Thus, between 1993 and 1999, Kodak gave birth to Eastman Chemical Company, American Cyanamid to Cytec Industries, Ciba-Geigy to Ciba Specialty Chemicals, Sandoz to Clariant, Monsanto to Solutia, and Rhone-Poulenc to Rhodia. Some more complex cases had to be solved differently. Hoechst, for example, proceeded in successive steps in 1994 it set up a fiftyfifty joint venture with Bayer, called Dystar, for the purpose of managing their respective dyestuffs businesses. In 1997 it transferred its specialty chemicals operations to Clariant in return for a 45 percent stake in the enlarged company finally, in 1999, it passed its industrial chemicals assets on to Celanese—the U.S. corporation it had acquired twelve years earlier—and passed Herberts, its coatings company, on to Du Pont.

For example, the Franco-American company Rhodia notes that REACH has reinforced its efforts in developing product stewardship programmes and reviewing SDS [526]. Similarly, the Swedish Chemical and Plastic Industry Federation has responded to REACH by launching a major initiative to improve SDS information supplied by its companies [527]. From the other end of the risk communication chain, the Dutch-American company Rohm and Haas has responded with a scheme for collecting data on the chemical contents of its upstream raw materials [528].

However, between 1998 and 1999, some dramatic shifts occurred as the result of a number of large mergers and acquisitions. On the one hand, Hoechst and Rhone-Poulenc spun off their traditional chemicals businesses (to become Cela-nese and Rhodia) and merged their life science divisions into a new entity (called Aventis). On the other hand, several other companies - mainly oil-based -merged their businesses in order to gain economies of scale. The result was that several new names appeared among 1999 s top ten BP Amoco, Dow/Union Carbide, ExxonMobil, and TotalFinaElf... 

Hoechst transformed its business from a hybrid chemical company into a pure Hfe science company by radically divesting over 80 percent of its portfolio, getting rid of businesses such as specialty chemicals (sold to Clariant) or chemical intermediates (spun off into Celanese). It completed the acquisition of Roussel-Uclaf and bought Marion MerreU Dow, and finally merged with the French life science company Rhone-Poulenc after the latter had also spun off aU its chemical business as Rhodia. By reinventing" itself under the brand name Aventis, it increased its Return on Sales (ROS) from 4.6 percent to 12.4 percent, a development that has recently been viewed very favorably by capital markets. 

Other companies have studied and developed proprietary formulations, but in general catalytic systems belong either to the antimonate family (Standard Oil, Rhodia, BASF, Nitto, Monsanto) [34—38] or to the molybdate family (Mitsubishi, Asahi).

The life science activities comprised a number of wholly and partially owned companies producing pharmaceuticals, agrochemicals and animal health products. A separate company called Rhodia was set up in June 1998 to operate in the field of specialty chemicals (fine organics, consumer specialties, industrial specialties, polyamides). 

Consolidation has continued among producers of flame retardants. Apart from the Great Lakes activity recorded above, Akzo acquired the phosphorus FR activities of Courtaulds. Albright Wilson (A W) sold their red phosphorus business to Clariant. The next year A W accepted an offer from Rhodia via an Austrian company, ISPG to acquire the phosphorus chemistry activities, including FRs. This was the outcome of a bidding contest between Rhodia and Albemarle. The A W purchase makes Rhodia the world s largest operator in speciality phosphate chemicals.

The global supply of cellulose acetate fibers is controlled by a few companies. These companies produce both tow and textile fibers. Celanese Acetate holds 29% of the world supply. Voridian, a division of the Eastman Chemical Co., follows with a 24% share. The remaining 32% of supply is manufactured by Rhodia, Daicel, Mitsubishi Rayon, and Acordis. There has been a recent trend of these companies closing down their smaller flake-production units and getting their product from larger and more efficient locations (104).
