Potential industrial applications

Nevertheless, there are various entry reactions into simple pyranoid derivatives (Scheme 2.10) with which to exploit their industrial application potential. 

As with all of die processes described, drese are first studied in detail in the laboratoty with an industrial application as dre objective. Those processes which pass the criterion of economic potential are used in a pilot plant smdy, and dretr, if successful, at the production level which must be optimized. The materials which are produced are mainly, in the present instance, for application in the elecU onics industry where relatively high costs are acceptable. It will be seen drat the simple kinetic theory of gases is adequate to account for dre rates of these processes, and to indicate the ways in which production may be optimized on dre industrial scale. 

Thus far the importance of carbon cluster chemistry has been in the discovery of new knowl edge Many scientists feel that the earliest industrial applications of the fullerenes will be based on their novel electrical properties Buckminsterfullerene is an insulator but has a high electron affinity and is a superconductor in its reduced form Nanotubes have aroused a great deal of interest for their electrical properties and as potential sources of carbon fibers of great strength 

Enzymes are generally classified into six groups. Table 1 shows typical polymers produced with catalysis by respective enzymes. The target macromolecules for the enzymatic polymerization have been polysaccharides, poly(amino acid)s, polyesters, polycarbonates, phenolic polymers, poly(aniline)s, vinyl polymers, etc. In the standpoint of potential industrial applications, this chapter deals with recent topics on enzymatic synthesis of polyesters and phenolic polymers by using enzymes as catalyst. 

Currently there are fewer than ten major dryer manufacturers around the world that offer SSD technology on a commercial scale. Often, it is necessary to custom design an SSD for a new application, which may involve a new dryer type or an application to a new product. The author has presented an extensive review of principles, practice, industrial applications, potential new applications, market penetration potential, and research and development (R D) needs for SSD technologies [1]. Special consideration is given to potential hcations for use of electricity and reuse of the exhaust steam from an SSD. Kumar and Mujumdar have provided an extensive bibliography and discussed the basic principles and hcations of SSD [2]. 

Muller et al. have also examined the enantioselectivity and the stereochemical course of copper-catalyzed intramolecular CH insertions of phenyl-iodonium ylides [34]. The decomposition of diazo compounds in the presence of transition metals leads to typical reactions for metal-carbenoid intermediates, such as cyclopropanations, insertions into X - H bonds, and formation of ylides with heteroatoms that have available lone pairs. Since diazo compounds are potentially explosive, toxic, and carcinogenic, the number of industrial applications is limited. Phenyliodonium ylides are potential substitutes for diazo compounds in metal-carbenoid reactions. Their photochemical, thermal, and transition-metal-catalyzed decompositions exhibit some similarities to those of diazo compounds.
