Abstract

Disclosed is a microwave chemical reaction apparatus comprising a means for heating a reaction solution, which is capable of irradiating the reaction solution with microwaves while controlling the output power according to the temperature of the reaction solution, and a means for forcibly cooling the reaction solution on the outside. The microwave chemical reaction apparatus is characterized by being capable of precisely controlling the reaction temperature. In this microwave chemical reaction apparatus, the reaction temperature can be controlled precisely, for example, within +-1 1 DEG C of a predetermined temperature, and thus this apparatus can be applied to precise chemical reactions. Since reactions proceed rapidly in such an apparatus, mass production can be achieved by a relatively small-sized reaction apparatus.

Description

technical field

[0001] The invention relates to a chemical reaction device using microwaves as a heating source. Background technique

[0002] Microwaves are one type of electromagnetic waves. Microwaves range from 0.3 to 30 GHz in frequency and 1 cm to 1 m in wavelength. They have been used in radar and communication equipment until now. Moreover, as seen in household electronic microwave ovens, as cooking utensils, it is widely used, especially in the field of food processing and drying of substances. Furthermore, microwaves are electromagnetic wave energy far weaker than visible light and infrared energy, and have been widely used in the field of chemistry until now mainly for the analysis of chemical substances such as magnetic resonance apparatus (NMR).

[0003] Recently, however, there has been a growing trend to perform organic chemical reactions using microwaves. This is a phenomenon in which electromagnetic energy of microwaves is absorbed by a dielectric (a subst...
