Many chemical products are now available through the reaction in the reactor. The reactor is simply a huge reaction vessel, and the raw materials are placed in a reaction vessel to obtain a desired product. In the case of chemical reactions, it is necessary to pay great attention to the reaction vessel. Generally, the air (oxygen) inside is replaced by nitrogen before the reaction. Or, the reaction kettle is continuously filled with nitrogen gas during the reaction.
Nitrogen is an inert gas that is less prone to chemical reactions. The protection of nitrogen ensures that no oxidation reaction will occur during the reaction, which will affect the quality of the product, and other adverse conditions caused by severe chemical reactions can be avoided. From the perspective of effectiveness and cost, the use of nitrogen replacement is the best choice.
