Coupled technologies

Nitric acid oxidation is used where carbohydrates, ethylene glycol, and propylene are the starting materials. The diaLkyl oxalate process is the newest, where diaLkyl oxalate is synthesized from carbon monoxide and alcohol, then hydrolyzed to oxahc acid. This process has been developed by UBE Industries in Japan as a CO coupling technology in the course of exploring C-1 chemistry.

COUPLING (Chemical). Reactions for the formation of chemical compounds usually by establishing a valence bond between a carbon atom and a nitrogen atom. Phenols and several other organic substances are also said "to couple. Polyphenylene oxides, thermoplastic materials, are produced by means of oxidative-coupling technology. 

Indole-fused, or indole-benzo-fused azepinone derivatives have attracted synthetic attention and examples include the preparation of 85 in 84% yield from 84 by intramolecular Heck coupling [01SL848], as well as the preparation of paullone 87 (a CDK inhibitor) by cyclisation of 86 under basic conditions borylation/Suzuki coupling technology was used to access 86 [02JOC1199]. Acid-catalysed cyclisation with polyphosphoric acid was used to prepare the racemic reduced azepino[4,5-6]indoles 92a,b from the precursors 91, which were obtained in turn from CDl-mediated coupling of 88 and 89, followed by reduction of the amide with lithium aluminium hydride [01H1455].

The R D activities are and will be performed under several work packages, such as a basic chemistry, an evaluation of alternatives, a process development, an equipment development, a material database, a catalyst development and database, and a hydrogen process coupling technology. 

This chapter reviews the principles of electrokinetic remediation (the EK process) and various chemical redox-related processes and introduces some selected studies on a variety of environmental contaminants treated by the EK process alone or by EK-coupled technologies. As indicated above, the EK process is a versatile technology. It has many advantages over other physicochemical technologies for in situ remediation of a variety of environmental contaminants. In particular, the EK process could be used in low hydraulic conductivity media and below buildings. Inevitably, the EK process per se has limitations. 

LC-NMR coupling technology has been recently reviewed [23], and the interested reader is also referred to the detailed text edited by Albert [24]. The miniaturisation of flow probes to the capillary scale has been developed to enhance signal detection sensitivity, as discussed in Section 3.4.2, and more recently the hyphenation of gas chromatography with microflow cells (GC-NMR) has even been demonstrated [25].
