Problems solved by technology

[0002] Most of the current chemical reaction experiments are water bath heating or electric heating. The power of microwave generators can be continuously adjusted, but they have not been applied to chemical reaction devices.
In addition, microwaves can only completely pass through materials such as glass, ceramics, polytetrafluoroethylene, and polypropylene plastics. It is very expensive to manufacture a reaction device that can withstand high pressure. For pressures greater than 10Mpa, almost only sapphire reactors can be used, and the price is very high. expensive
In recent years, high-pressure resistant quartz glass has been produced in China, and the cost is relatively low, but it has not been introduced into microwave chemical experiments.

Abstract

A visual high-pressure microwave heating chemical reactor is composed of microwave generating / controlling / transmitting system, chemical reactor, constant-temp system and reactive gas I / O and metering system. Said chemical reactor consists of stainless steel jacket, protecting stainless steel rings, high pressure resistant glass cylinder, high pressure resistant microwave guide and enclosing head.

Description

technical field [0001] The invention relates to a high-pressure visible microwave chemical reaction device. Background technique [0002] Most of the current chemical reaction experiments are heated by water bath or electric heating. The power of the microwave generator can be continuously adjusted, but it has not been applied to the chemical reaction device. In addition, microwaves can only completely pass through materials such as glass, ceramics, polytetrafluoroethylene, and polypropylene plastics. It is very expensive to manufacture a reaction device that can withstand high pressure. For pressures greater than 10Mpa, almost only sapphire reactors can be used, and the price is very high. expensive. In recent years, high-pressure resistant quartz glass has been produced in China, and the cost is relatively low, but it has not been introduced into microwave chemical experiments. Contents of the invention [0003] The purpose of the present invention is to provide a bran...
