Abstract

With its twelve guiding principles, green chemistry calls for modifications to traditional chemical synthesis and the use of less hazardous raw materials. Green Chemistry aims to make synthetic processes more effective using less harmful solvents, fewer steps in the process, and as little waste as is practically possible. This is how chemical synthesis will be a component of the sustainable development approach. Since the initial papers on microwave irradiation's use to synthetic chemistry, it has been obvious that this approach will have a significant impact on all facets of this field. Reaction times were sped up, yields were enhanced, selectivities were changed, product purity increased, and work-up procedures were made simpler, and in most cases, these conditions and outcomes could not be obtained using conventional heating. Because one component of the reaction strongly absorbs microwave radiation, this methodology can be incorporated into the idea of green chemistry. This results in faster reaction times and greater energy efficiency. Additionally, the synergy of this unconventional energy source with solvent-free conditions, solid catalysts, and environmentally friendly solvents has increased the scope of its green applications. The Use Of Thermal Microwave Irradiations To Achieve Rapid Heating & High Bulk Reactions Is Vital To This Method. Reaction vessels are used to carry out the microwave synthesis. Instead of using Borosilicate glass, this process uses the silicon carbide (SiC). Nanomaterials, nanocatalysts, and prototype equipment are used to carry out the microwave assisted synthessis. Nanomaterials come in variety of Shapes including Nanorods, Nanoprisms, hexagons, spheres, and stars. Noble and transition metals can be synthesized in a repeatable manner using microwave assisted synthesis.[2,4,6]
