Description

Technical Field

[0001] The utility model relates to the technical field of chemical production and preparation, in particular to a cyclotron micro-reaction device for producing acetobutyrolactone. Background Art

[0002] Acetylbutyrolactone is an important organic chemical raw material, widely used in coatings, inks, adhesives, fragrances and other fields, and is relatively stable at room temperature. With the rapid development of related industries, the demand for acetylbutyrolactone is increasing, and higher requirements are also placed on its production process. The traditional production method of acetylbutyrolactone has problems such as long reaction time, high energy consumption, and low product purity. Therefore, the development of new, efficient and environmentally friendly production technology has become a hot topic in industry research.

[0003] Applying the cyclotron microreactor to the production of acetylbutyrolactone is expected to solve many problems in traditional processes, improve production efficiency, reduce costs, and reduce environmental pollution.
