Description

Technical Field

[0001] The utility model belongs to the technical field of ammonolysis reaction, and in particular relates to a chemical reagent auxiliary ammonolysis centrifugal device. Background Art

[0002] Ammonolysis reaction refers to the process in which organic compounds containing various functional groups generate amine compounds under the action of aminating agents. Ammonolysis reactions include ammonolysis of halogens, ammonolysis of carbonyl compounds, ammonolysis of hydroxyl compounds, ammonolysis of sulfonyl and nitro groups, and direct ammonolysis; in liquid phase ammonolysis, the reaction rate is closely related to the stirring effect. In the absence of stirring, the insoluble organic substrate with a relatively large relative density is deposited at the bottom of the reactor, and the reaction will occur at the interface between the two phases. For intermittent reaction equipment, an effective stirring device is required; for continuous reaction equipment, the flow rate must be controlled to make the reaction materials form a turbulent state.

[0003] Currently, centrifugal devices are widely used in the field of ammonolysis reactions. However, during the solid-liquid separation process of existing centrifugal devices, solid particles are prone to block the filter holes under the action of centrifugal force, which seriously affects the solid-liquid separation effect and the experimental efficiency, and is very inconvenient to use.
