Green catalytic processes

Chapter 6 covers applications and case studies on the development of green catalysts and green processes. Three case studies are presented in this chapter highlighting the development of a green catalytic process and the application of a green catalyst in the treatment of industrial effluent. 

They observed that these complexes were remarkably active catalysts and the oxidation was fast, selective, require a small amount of catalyst and proceeds in the absence of any additional solvent or additives thus, making it a green catalytic process. 

These three steps all produce significant amounts of waste. First, as discussed earlier, the nitration process results in the production of spent sulfuric acid. In the past the company had been able to sell much of this material to the coke and steel industries but declining demand meant that the acid now required disposing of, at additional cost. At the time green catalytic nitration technology was becoming available with clay, zeolite and lanthanide catalysts all providing possible alternatives to the use of sulfuric acid (see below). Improved selectivity to the desired para-isomer is an added benefit of some of these catalytic systems. However on the...

The outlook of syntheses, based on using SC-CO2 or appropriate IL/SC-CO2 biphasic system for developing integral green chemical processes due to the physical and chemical characterishcs of these neoteric solvents and the enhanced enzyme catalytic properties seems promising.
