Description

technical field [0001] The invention relates to a Raman liquid pool for studying the liquid phase reaction process under high temperature and high pressure, and belongs to the technical field of chemistry and chemical equipment. Background technique [0002] Compared with the solid-state high-temperature and high-pressure method, the solvothermal synthesis method has the advantages of low cost, mild reaction conditions (200-400 ° C, 50-300 atmospheres), and easy regulation of the reaction process. It has become the most inorganic functional materials, especially as The main synthesis method of non-oxide materials such as gallium nitride, cubic boron nitride and diamond, carbon nitride, etc., has an increasingly wide range of applications. However, there is a prominent problem in the solvothermal and hydrothermal synthesis methods: the research on the synthesis reaction process and reaction mechanism is basically still blank, which makes people lack the necessary basis for th...

Problems solved by technology

However, there is a prominent problem in the solvothermal and hydrothermal synthesis methods: the research on the synthesis reaction process and reaction mechanism is basically still blank, which makes people lack the necessary basis for the regulation of the reaction process, and wastes a lot of time, manpower and financial resources. To explore and optimize the preparation conditions

However, the solvothermal reaction is carried out in a closed high-temperature and high-pressure container, and it is difficult to monitor and control the reaction process. Therefore, it is very difficult to use Raman spectroscopy to study the liquid-phase reaction process under high-temperature and high-pressure conditions. Corresponding research results are very rare
