What is microwave heating?
Microwave energy is a form of electromagnetic energy. Its frequency can impact the realm of molecular rotations.
How is microwave heating useful in synthetic chemistry?
Glass is largely transparent to microwave energy, so, unlike traditional hotplates, reaction solutions are heated directly and volumetrically.
Because microwave heating is so efficient, temperatures up to 300 °C can safely be reached in a matter of minutes.
A higher reaction temperature means a shorter reaction time. Most microwave reactions are done in as little as 10 minutes instead of 8 hours or overnight.
Why use a dedicated scientific microwave reactor?
REPRODUCIBILITY– Scientific journals require temperature, pressure, and power reporting for publication. Specially tuned cavities and electromagnetic stirring ensure consistent results between reactions.
FLEXIBILITY – Novel accessories allow for automation of reaction runs, use of gaseous reagents, flow chemistry, and many other types of transformations. Pressurized reactions with low boiling solvents allow more choices when determining ideal synthesis and work up conditions.
SAFETY – Industrial microwave reactors have the hardware and software to ensure a safe working environment, even at high temperatures and pressures, and long instrument life span.
