Abstract

According to an aspect of the disclosure, there is provided a microwave reactor including a container for storing a bath fluid, a tube including an inlet at one end through which a target fluid is introduced, an outlet at another end through which the target fluid is discharged, wherein at least a portion of the tube is submerged in the bath fluid, and at least one radiator located outside the container and configured to irradiate microwaves into the container.

First claim

What is claimed is:

1. A microwave reactor comprising:
a container comprising a bath fluid disposed therein;
a tube including an inlet at one end though which a target fluid is introduced, and an outlet at another end through which the target fluid is discharged, wherein at least a portion of the tube is submerged in the bath fluid;
at least one radiator located outside the container and configured to irradiate microwaves into the container;
a temperature measuring unit configured to measure a temperature of the bath fluid within the container;
a cooling unit at least partially submerged in the bath fluid within the container and configured to cool the bath fluid; and
a temperature controller configured to control the temperature of the target fluid to correspond to an optimum reaction temperature range by controlling the temperature of the bath fluid by operating the cooling unit, based on the temperature measured by the temperature measuring unit;
wherein the microwaves irradiated from the at least one radiator heats the bath fluid and the target fluid together; and
wherein the temperature controller monitors the temperature of the bath fluid and operates the cooling unit when the temperature of the bath fluid is greater than a predetermined reference temperature to decrease the temperature of the bath fluid, thus the temperature controller regulates the temperature of the target fluid by regulating the temperature of the bath fluid.

2. The microwave reactor of claim 1 , wherein the container comprises at least one of a thermoplastic, glass, polytetrafluoroethylene (PTFE), perfluoroalkoxy alkane (PFA), methyl methacrylate, polyetherimide, aluminum oxide, and quartz.

3. The microwave reactor of claim 1 , wherein the bath fluid comprises at least one of water, C5-C10 alcohol, C2-C6 diol, C3-C6 triol, a polymer thereof, and a mixture thereof.

4. The microwave reactor of claim 1 , wherein the tube comprises at least one of a thermoplastic, glass, polytetrafluoroethylene (PTFE), perfluoroalkoxy alkane (PFA), methyl methacrylate, polyetherimide, aluminum oxide, and quartz.

5. The microwave reactor of claim 1 , wherein at least part of the tube, which is submerged in the bath fluid, has a spiral shape.

6. The microwave reactor of claim 1 , wherein a pressure regulator is arranged in the inlet.

7. The microwave reactor of claim 1 , wherein a pressure regulator is arranged in the outlet.
