The Hastelloy reactor is an instrument that is mainly used to carry out important catalytic reactions. It is made of an alloy called Hastelloy, which is a very heat-resistant metal material with good corrosion resistance and corrosion resistance, and one of the most important properties of this alloy is that it has strong oxidation resistance. Hastelloy reactor is usually composed of vertical and plate type two structures. The structure of the vertical reactor is simple, easy to operate, and the temperature and time can be changed during the reaction process to achieve a good reaction effect; The plate reactor uses a medium with good thermal conductivity, such as ceramics, to keep the reaction uniform and keep the data collection more accurate, which is conducive to reaction regulation and analysis. The reaction environment of Hastelloy reactor is easily controlled, the oxidation resistance is strong, and the reaction temperature can reach 400 degrees Celsius, which makes it safe to complete a variety of challenging catalytic reactions. In addition, due to the high corrosion resistance of Hastelloy alloy, it can be adapted to handle complex chemical reactions, including organic reactions, inorganic reactions, hydrothermal reactions, oxidation reactions and REDOX reactions, and the reaction results are also very reliable. Hastelloy reactor is not only suitable for chemical experiments, but also can be used in medicine, fine chemistry, metallurgy and environmental protection. In the field of medicine, it can be used to prepare drugs, such as anti-cancer drugs; In the field of fine chemistry, it can be used to synthesize various organic compounds; In the field of metallurgy, it can be used to prepare high purity metal materials; In the field of environmental protection, it can be used to treat harmful substances and impurities in waste gas, thereby protecting the environment. As can be seen from the above introduction, Hastelloy reactor has many characteristics, can meet a variety of challenging reaction requirements, is an important modern chemical instrument. Of course, its use is far more than that, and more application space is yet to be developed. With the development of technology, the development of Hastelloy reactor will also become an important driving force for the development of chemical science
