Abstract

MICROWAVE-ASSISTED SYNTHESIS & GREENER WORLD: A REVIEW REPORT

Dr. Amit Dwivedi*

.

Abstract

This review paper reports the Microwave-assisted solvent free synthesis and there advantages towards a cleaner and greener world. The Microwaves have wavelength in the range of 1 mm to 1 m, corresponding to frequencies between 30 and 3 GHz. Microwave heating is technique that involves electromagnetic waves and consequent heat transfer. When an electric field is applied to a conductive material it causes flow of electricity. Further, a timevarying electric field starts back and forth motions leading to oscillations in dipolar molecules, such as water etc. Similarly, the application of a time-varying magnetic field to a conductive material also induces current to flow. The popularity of microwave irradiation methodology is increasing rapidly as it opens new avenues from conventions heating technique to modern eco-friendly, cheaper, quicker and safer path way for solvent-free molecular synthesis. A scope of using a variety of supporting agents, and cycloaddition, cyclocondensation reactions has also been established.

Keywords: Microwave heating, electromagnetic waves, dipolar molecules, cycloaddition, cyclocondensation.
