At the present time, catalytic reactions in supercritical carbon dioxide for the manufacture of fine chemicals appear to be more commercially feasible (McCoy, 1999). A large range of reactions have been investigated in cooperation with the University of Nottingham and Thomas Swan Co., Ltd. (Consett, Co. Durham, U.K.) (Meehan et al., 1999). Very high space-time...

The technology has been commercialized, in collaboration with the Thomas Swan company, for the manufacture of trimethyl cyclohexanone by Pd-catalyzed hydrogenation of isophorone (Fig. 7.22) [77]. 

The Thomas Swan Co. plant went on stream in June 2002 and produces 1000 tonnes of product per year. As can be seen in Figure 10.6, the purity of the... 

The improved reaction rates achieved in the SC-CO2 medium combined with the variety of substrates considered so far illustrate the potential of this technology. As an indication of the economic viability of CO2 processing in the fine chemical industry, a plant has been constructed at Thomas Swan and Co. in the The plant has been built for hydrogenation processes to produce fine chemicals and pharmaceutical intermediates to a rating of 1000 kg hr of CO2 at pressures up to 500 bar. However, the significant capital cost of supercritical processes, combined with the complex production and expensive nature of chiral products, demand that SC-CO2 be considered for asymmetric hydrogenation. 

SCCO2 is largely used to process food (extraction or fractionation), but other applications, such as the fluoropolymer synthesis by DuPont, hydrogenation or alkylation by Thomas Swan, coatings by Union Carbide, and polyurethane processing by Crain Industries, are still in development [111]. The application of supercritical fluids (SCFs) as reaction media with homogeneous catalysts has been mainly investigated on a laboratory scale. 

Poliakoff and co-workers developed a catalytic hydrogenation process which has been commercialized by Thomas Swan and Co. for the manufacture of trimethylcy-clohexanone by Pd-catalyzed hydrogenation of isophorone (Equation 4.29) [52],... 

The photograph in Figure 4-14 shows a Nippon Sanso horizontal reactor in operation at temperature. They use an inverted geometry with full rotation of the susceptor and offer units which handle up to three 100 mm or one 200 mm wafer(s) and offer cassette-to-cassette wafer susceptor transfer. Several other vendors, e.g., Thomas Swan or Aixtron, market horizontal tube systems. CVTis also a well-known horizontal tube system manufacturer and one of the few vendors specializing in HgCdTe systems.
