Abstract

The invention relates to a continuous flow microreactor, a manufacturing method and an application. The continuous flow microreactor comprises a pipe body, one end of the pipe body communicates with afeeding pipe and an air inlet pipe, the other end of the pipe body is open, a microreactor unit is arranged in the pipe body, and a plurality of micron-sized pore channels are distributed in the microreactor unit; the microreactor unit is made of a nano ferrite magnetic material, the microreactor unit comprises a preheating section and a catalytic reaction section which are distributed in the length direction of the pipe body, and the catalytic reaction section is close to the open end of the pipe body; and an induction coil sleeves the pipe body, two ends of the induction coil are electrically connected with a high-frequency power supply, and the magnetic heating effect of nano magnetic particles in an external alternating magnetic field has the advantages of high efficiency, easiness incontrol, targeting and the like, and has the advantages of good temperature uniformity, low energy consumption, high efficiency, simple structure, convenience in use, easiness in system integration and scale amplification and the like. High-purity and high-yield synthesis of a target product in a fine chemical product process can be realized.

Description

technical field

[0001] The invention relates to a continuous flow microreactor, a manufacturing method and its application, in particular to a continuous flow microreactor, a manufacturing method and its application in the production process of medicines and fine chemicals, and belongs to the technical field of microreactors and their preparation and application. Background technique

[0002] In the past decade, continuous catalytic reactions have become one of the most active research areas in the fields of pharmaceuticals and fine chemicals. During the continuous reaction process, only one operation step and one purification step are required, which can greatly improve the synthesis efficiency. However, the traditional stirred tank reactor has problems such as low reaction efficiency, serious waste of resources, lack of environmental protection, and difficulty in scaling up due to mass transfer limitations, making it difficult to transform into industrial scale production. ...
