Description

Technical Field

[0001] The invention relates to the technical field of purification, in particular to a method and equipment for purifying benzylaminopurine. Background Art

[0002] Benzylaminopurine is a synthetic cytokinin. The pure product is a white crystalline powder. It can promote cell division, induce tissue differentiation, delay aging, and protect flowers and fruits. It is widely used in food crops, cash crops, etc. in agricultural production to increase yield and quality. It is used for reproduction and cultivation in the field of horticultural flowers and is a commonly used growth regulator in tissue culture.

[0003] The patent application with application number CN202310372780.1 discloses a purification method and purification equipment for benzylaminopurine, comprising the following steps: step 1: adding a solvent to a crude benzylaminopurine product, wherein the mass ratio of the crude benzylaminopurine product to the solvent is 1:12 to 20, and stirring to dissolve; step 2: filtering the benzylaminopurine solution obtained in step 1 with a filtering device, standing, filtering after natural crystallization, washing with a solvent and then drying.

[0004] In summary, in the process of purifying the benzylaminopurine solution, the insoluble impurities in the benzylaminopurine solution need to be filtered. To this end, the solution containing benzylaminopurine needs to be flow-filtered in a variety of tanks. However, when the benzylaminopurine solution being filtered flows between different tanks, it may crystallize due to the decrease in ambient temperature, and the crystals may adhere to each other to form agglomerates, which will reduce the fluidity between the crystals, thereby causing blockage and difficulty in operation, which is not conducive to subsequent processing.
