Description

Technical Field

[0001] The present application relates to the technical field of purification equipment, and in particular to a high-efficiency purification device for methyl 3-(4-hydroxyjasmine) propionate. Background Art

[0002] Purification is the process of separating impurities from a mixture to increase its purity. As an important chemical method, purification plays a vital role not only in chemical research but also in chemical production. Many important chemical research and production processes are centered around purification.

[0003] Currently, a Chinese patent publication with publication number CN210145613U discloses a purification device for preparing high-purity 5-aminoisophthalic acid dimethyl ester, comprising a body, a cover, a feed port, and a discharge port. The cover is hingedly connected to the top of the body, and the feed port is fixedly welded to a side surface of the body. The stirring paddle, when rotating, filters large particles from the chemical raw materials through a coarse-mesh filter, effectively preventing the chemical raw materials from adhering to the bottom of the inner cavity of the body during the purification process, making it more convenient to use. The gas in the exhaust pipe condenses into water droplets upon cooling and is collected in a condensation tank. The condensed water is discharged through a drain port, increasing purification output and reducing environmental pollution. The purified chemicals are discharged through the discharge port. The filter can be replaced by opening the cover, making it more convenient to use and also improving the purification accuracy of the chemical raw materials.

[0004] In actual use, it was found that the existing purification device could not control the discharge speed during discharge, which easily led to more or less discharge, and thus made it inconvenient to collect the purified material. Therefore, we proposed a high-efficiency purification device for methyl 3-(4-hydroxyjasmine) propionate to solve the above problem. Utility Model Content
