Microwave assisted pyrolysis of urea supported on graphite under solvent-free conditions

The coupling of graphite (support) with microwaves (energy source) is responsible for a high temperature gradient leading to increased reaction rates as compared to conventional procedures. A rapid one-pot preparation of cyanuric acid is described that proceeds from urea by pyrolysis using microwave heating in the absence of water and organic solvents. (C) 2001 Elsevier Science Ltd.
