Abstract This paper deals with the
contribution of microwave heating to organic synthesis, especially to esterification. When the reaction is conducted in a
heterogeneous medium and under microwave heating, the reaction rate increases
compared to classical heating under the same conditions. This is due to
selective heating of the catalyst particles creating hot spots, resulting in
an increased reaction rate. The temperature of the reactive site was
calculated to be 9-18 K above the bulk temperature. A new continuous flow
microwave reactor has been tested in order to show the role of selective
heating of the catalyst in the activation of organic reactions under
microwave heating. Key Words: Esterification, Microwave, Solid catalyst, Continuous reactor, Selective
