Description

technical field [0001] The invention relates to the technical field of fluorination reaction, in particular to an online multiple fluorination system. Background technique [0002] Fluorination is the process of making metal oxides react to form metal fluorides in the metallurgical industry, thereby extracting metal elements from the original oxides, that is, the fluorination metallurgical process. As transition products, metal fluorides are widely used in the industrial production of metals, especially rare metals. The negative values ​​of the formation isobars of metal fluorides are quite large, larger than those of the corresponding chlorides. Metal fluorides have the advantages of easy formation of complexes, relatively high stability, and relatively low vapor pressure. In addition, they are easy to prepare into pure compounds, easy to reduce, and have low melting and boiling points. Therefore, in the process of extracting metals by molten salt electrolysis is particul...

Problems solved by technology

[0003] The interaction between fluorine and organic compounds is a strong exothermic reaction, and its reaction efficiency needs to be improved. At the same time, a large amount of heat released during the fluorination reaction can damage the molecular structure of the reactant. If the heat of reaction cannot be reduced, it will not only cause certain damage to the equipment damage, and even cause safety accidents such as explosions. Most fluorinating agents are highly corrosive and polluting, and directly discharge the waste gas after the fluorination reaction into the atmosphere, which will not only have a certain impact on the health of the staff , but also pollute the air environment
