Alternative green chemistry application

Additionally, the environmental issue of utilizing waste cellulosic material and waste biomass products should be considered as an alternative green chemistry application to the production of many value added products. The combinatorial utilization of carbohydrate scaffolds based on chiral building block functionalization will also constitute attractive and relatively cheap starting materials. This rich selection of potential approaches, combined with further developments of new procedures and modem reagents, creates an enormous opportunity for the field to be at the frontier for many years to come.

SECTION 18.5 The green chemisiry initiative promotes the design and application of chemical products and processes that are compatible with human health and that preserve the environment The areas in which the principles of green chemistry can operate to improve environmental quality include choices of solvents and reagents for chemical reactions, development of alternative processes, and improvements in existing systems and practices.

Nevertheless, alternative or nontraditional methods are interesting fields for new applications, due to the need for more selective synthetic and environmentally friendly methods, including the aspect of reaction media (solvent) and energy transfer into a reaction system. The use of supercritical fluids (SCFs) or ionic liquids (IL) as process solvents is well established. From the view point of green chemistry or sustainable chemisfiy, it is SCFs, especially supercritical carbon dioxide (SCCO2), that are the main focus [2, 3]. It is currently under discussion whether ioiuc liquids as alternative process solvents are beneficial. In general, more fundamental problems, like recovery, reuse, purification and ecology (eco-toxicity), have to be solved.
