Technical Field

[0001] The utility model belongs to the technical field of trifluoromethanesulfonyl chloride synthesis equipment, in particular to a fixed bed equipment for synthesizing trifluoromethanesulfonyl chloride. Background Art

[0002] Fixed-bed reactors are a type of reactor commonly used in the chemical, petrochemical, and energy industries. They operate by immobilizing a catalyst or adsorbent within the reactor bed, allowing reactants to react or exchange through the bed. They are generally used for gas-solid reactions and are particularly well-suited for chemical reactions requiring catalysis, such as the synthesis of trifluoromethanesulfonyl chloride. By providing a stable, continuous reaction environment, fixed-bed reactors enable the efficient conversion of reactants into trifluoromethanesulfonyl chloride under the action of the catalyst.

[0003] In the synthesis of trifluoromethanesulfonyl chloride, a catalyst is placed within a reactor, and gaseous reactants pass through a fixed-bed catalyst layer to react and produce the target product. Since the reactants come into contact with the catalyst within the fixed bed through the reactor's air inlet and feed ports, which are typically small, it takes time for the reactants to disperse within the fixed bed, thus affecting the synthesis efficiency of trifluoromethanesulfonyl chloride in the fixed bed.
