Future trends in green chemistry oxidation reagents and catalysts lolvk

ABSTRACT This present study is an attempt to provide some information on the role of catalysts in green synthesis of chemicals for sustainable future. Catalysis plays a vital role in the As the label indicates, the pie chart shows a distribution of green chemistry topics as analyzed by articles produced in the year 2008. The majority of the pie chart (about 50%) is attributed to catalysis – or starting a reaction, under more favorable conditions that require less resources, whether those resources are heat, energy, reagents etc. When this is done many catalysts may be made in a non-green manner, although when used they replace stoichiometric reagents and so overall they are at best partially green. In recent years catalysis by gold has stated to play a major role with respect to green chemistry and examples can be readily found that address the following 8 out of the

Abstract: Recent advances in the development of environmentally friendly recyclable reagents and catalytic systems based on hypervalent iodine are discussed. 25 years ago catalysis was highlighted as a main principle of Green Chemistry. Selective catalysis enables an efficient utilisation of resources and the design of benign processes. Waste formation caused by stoichiometric reagents, for instance in reduction or oxidation reactions, can be overcome using suitable catalysts and benign reductants and includes reagents, solvents losses, all process aids and, in principle, even oxidation of a secondary alcohol to the corresponding ketone are compared in Fig. 1.1.

Future developments in catalysis will propel the pursuit of green chemistry forward. The design of catalysts that both activate otherwise inert starting materials as well as enhance reaction rates will reduce the current reliance on reactive and toxic reagents. Future trends in green chemistry: Oxidation reagent and catalysis: historically, many of the oxidation reagents and catalysts have been comprised of toxic substances such as heavy metals. Market Analysis. Green Chemistry is the new philosophical idea processed for a sustainable environment from non-polluting substances. The future trends on green chemistry is for safer products which does not affect the environment and the success is depends on the new chemists and chemical industry. Catalysis can not only help to green chemical processes (e.g., by replacing reagents or by enabling more efficient processes) but the demonstration of their value—to reduce the environmental impact of processes and reduce the costs of the processes—will catalyze the greening of chemistry.
