High pressure flow reactor with window for arrangement in ultraviolet visible spectrometer

Abstract

The invention discloses a windowed high-pressure reacting kettle able to placed in ultraviolet-visible spectrometer, having a tube shell, the tube body of the shell is an inter-wall structure to form a circular inter-wall cavity, there is a tube space in the shell and there is a high-temperature and high-pressure resistant tube body of reacting kettle in the tube space; outside the tube body of the reacting kettle, an electric heating device is fixed on the inner wall of the shell; sealed pressure caps are set on two ends of the tube body of the reacting kettle to make the reacting kettle compose a sealed cavity, there are two opposite holes made on the pressure caps, there is a high-pressure quartz window sealed on each hole, and there are fluid inlet and outlet set on the reacting kettle. It is an open reacting kettle and can accurately determine the temperature and pressure of the measured fluid and also make real-time ultraviolet atlas determination on the fluid during high-temperature and high-pressure reaction.

Description

technical field [0001] The invention provides a container for a measured fluid which can be placed in an ultraviolet-visible spectrometer, in particular a windowed high-pressure reactor which can be placed in an ultraviolet-visible spectrometer. Background technique [0002] Under extreme conditions, hydrothermal research and chemical reaction engineering need to understand the properties of high-temperature and high-pressure solutions, and one of the basic methods to understand the properties of this high-temperature and high-pressure solutions is to measure its ultraviolet spectrum. The ultraviolet-visible spectrometer in the prior art Generally, high-temperature and high-pressure substances cannot be measured. The container containing the fluid to be tested has a closed cavity, and the cavity of the container containing the fluid to be measured has a window on the wall of the cavity, and the window is sealed and fixed. A material, such as glass or quartz, can thus be used...

AI Technical Summary

Problems solved by technology

It is relatively easy to measure the spectrum of a fluid with known composition under saturated pressure, but it is not easy to measure the properties of the flowing fluid or the reaction of the solid system in a high temperature and high pressure reaction process in real time
