有机合成过程中微波的作用

微波化学值得研究:
Microwave chemistry is not “voodoo science”, but in essence an incredibly effective, safe, rapid, and highly reproducible way to perform an autoclave experiment under strictly controlled processing conditions.
但是:
Most of today's commercially available laboratory microwave reactors are not very well suited to study microwave effects.These instruments were essentially designed to “rapidly generate compounds”, not to perform accurate kinetic investigations. Therefore, in most instances, these microwave reactors are not equipped with the temperature-sensing technology and software algorithms that are needed to accurately control and monitor reaction temperature during a microwave chemistry experiment (taking all eventualities such as viscosity increases, exothermic behavior, and changes in the microwave absorptivity of the reaction mixture into account).
