Lab pressure reactor factory introduces the steps of using the reactor. 1. Before use ① Scientific operating procedures should be formulated for experiments using hydrothermal reactors, including standardized installation, reaction, disassembly, cleaning and other operations, and scientific prediction of possible side reactions and hidden dangers of reactants, products, cleaning materials and other components.

1. Before use

① Scientific operating procedures should be formulated for experiments using hydrothermal reactors, including standardized installation, reaction, disassembly, cleaning and other operations, and scientific prediction of possible side reactions and hidden dangers of reactants, products, cleaning materials and other components.

② For the reactor used for the first time, soak the inner lining with 100℃ water for no less than 30 minutes before use. Make the molecular structure more stable, remove surface and inner wall impurities, and effectively prevent shrinkage and fluffing.

③ Check for cracks, wear, corrosion, etc. If the jacket is broken, and the inner tank is worn or corroded, the kettle should be replaced with a new one in time and the experiment should be carried out again.

④ Reactor accessories should be properly managed to ensure that it is a complete set of reactors, and accessories cannot be mixed.

2. In use

① When filling the reactor and taking out the reactor after the reaction is completed, protective equipment such as lab coats, goggles, protective gloves, protective covers, and respiratory protection equipment should be worn/wearing.
② When the oven starts to heat up, people in the room must stay away to prevent the explosion from hurting people!

③ Heat up to the required reaction temperature according to the specified heating rate (recommended ≤5°C/min).

④ Keep a certain distance between the reactor and the heating source.

⑤The inner tank of the reaction kettle should not exceed the specified value (see the attached table), and the reaction of releasing gas and exothermic heat is strictly prohibited in the kettle. Do not use nitric acid to react with organic raw materials, so as not to generate explosive nitro compounds.

3. After use

① After the reaction is completed, make sure that the temperature and pressure in the kettle are in a safe range before unscrewing the lid of the kettle. Never use brute force to open the reactor.

② Generally use a bench vise + face protection + hand protection to open the reactor.

③ Lab pressure reactor factory reminds you: You should choose a suitable cleaning agent for cleaning according to the reactants and products to avoid side reactions during cleaning. It is strictly forbidden to use nitric acid, perchloric acid, etc. for hydrothermal cleaning. Do not scratch with metal sharps when cleaning, and be careful not to damage the kettle cover line, sealing strip, etc. The kettle body and lining are combined and stored in a ventilated and dry place.
