Technical Field
[0001] The utility model relates to the technical field of sulfolane production, in particular to a sulfolane continuous production device. Background Art
[0002] The traditional sulfolane production process uses a kettle reaction process, but this process has obvious disadvantages. In the reactor, the reactants rely on stirring to increase the contact area with each other, but the speed of the stirrer cannot be increased infinitely, which limits the reaction effect.
[0003] Cyclobutene sulfone is synthesized by reacting excess sulfur dioxide with butadiene. However, the excessive use of sulfur dioxide not only increases production costs, but also makes subsequent waste gas treatment more difficult.
[0004] In the synthesis process of cyclobutene sulfone, the reaction effect is poor due to insufficient material reaction, which directly leads to the reduction of product purity. At the same time, due to untimely heat exchange during the reaction, safety accidents are easily caused, which is also an important aspect of the process that needs to be improved. In view of this, in-depth research on the above issues led to the creation of this case. Utility Model Content
