Hydrothermal reactors and hydrothermal crystallization reactors are two types of equipment commonly used in laboratories and industrial production, with some differences in their principles, structures, and applications. This article will provide a detailed introduction to both from these aspects

A hydrothermal kettle is an equipment used for high-temperature and high-pressure reactions, mainly utilizing the high temperature and pressure under hydrothermal conditions to accelerate the reaction rate of substances. It usually consists of a pot body, a heater, a temperature control system, a pressure control system, and a stirring device. A hydrothermal kettle can perform various experiments and production processes such as solvent pyrolysis, catalytic reactions, and crystal growth. It is widely used in fields such as chemistry, materials, pharmaceuticals, etc

The hydrothermal crystallization kettle is mainly used for crystal growth and material preparation. It utilizes a high-temperature and high-pressure hydrothermal environment under hydrothermal conditions to precipitate crystals through solution reactions. A hydrothermal crystallization kettle usually consists of a kettle body, a heating system, a pressure control system, and a stirring system. It can control the morphology and size of crystals, which is of great significance for research that requires high-purity and specific shape crystals

The difference between hydrothermal kettle and hydrothermal crystallization kettle is mainly reflected in the following aspects: 

1 Different application fields: hydrothermal reactors are widely used in solvent pyrolysis, catalytic reactions, and crystal growth experiments and production processes, while hydrothermal crystallization reactors are mainly used for crystal growth and material preparation

2. Different reaction principles: The hydrothermal reactor utilizes the hydrothermal conditions under high temperature and pressure to accelerate the reaction rate of substances, while the hydrothermal crystallization reactor uses the hydrothermal environment under high temperature and pressure to prepare crystals through the reaction solution

3. Different equipment structures: There are some differences in the structure between hydrothermal reactors and hydrothermal crystallization reactors. A hydrothermal kettle usually consists of a pot body, a heater, a temperature control system, a pressure control system, and a stirring device, while a hydrothermal crystallization kettle mainly includes a pot body, a heating system, a pressure control system, and a stirring system

4. Different usage methods: There are also differences in the usage methods between hydrothermal reactors and hydrothermal crystallization reactors. A hydrothermal reactor relies on a heating system and a temperature control system to achieve high temperature and high pressure reaction conditions, while a hydrothermal crystallization reactor places more emphasis on controlling the composition of the solution and reaction parameters

Overall, there are some differences in the principles, structures, and applications between hydrothermal reactors and hydrothermal crystallization reactors. Choosing appropriate equipment for different experimental and production needs can improve work efficiency and accuracy of research results. They all play important roles in fields such as chemistry, materials, and pharmaceuticals, and have a positive driving effect on the development of related industries.
