Problems solved by technology

[0006] The object of the present invention is to provide a kind of crystallization method for the preparation of biomedicine, to solve the problem in the above-mentioned background technology that in the prior art, when utilizing the crystallization equipment for biomedicine preparation to carry out the crystallization treatment, the cold water is transferred from the crystallization equipment The top is slowly dropped into the crystallization equipment, the cold water will be in contact with the solvent at the top of the crystallization equipment, and it cannot be quickly mixed with the solvent in the crystallization equipment, so that the top is crystallized first, and the reaction product is prone to crystallization. The phenomenon of inhomogeneous crystals affects the crystallization preparation of biomedicine

Abstract

The invention discloses a crystallization method for biological medicine preparation in the technical field of crystallization methods for biological medicine preparation. The method comprises the following specific steps: step 1, measuring a biological medicine solvent needing to be crystallized; 2, taking out enough cold water for later use; 3, adding a biological medicine solvent and cold water into crystallization equipment for biological medicine preparation; and 4, discharging the crystallized solution and crystals, and collecting the crystals. The crystallization equipment for biological medicine preparation is used for medicine crystallization, so that a solvent in the crystallization cylinder can be quickly and uniformly separated out, and the crystallization efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a crystallization method for biomedicine preparation, in particular to a crystallization method for biomedicine preparation. Background technique [0002] For the biomedicine prepared step by step by solution reaction, after the reaction is completed, the solution needs to be cooled and crystallized until the corresponding product is obtained. Usually, two methods are used, and two different effects will be obtained. One is to use When the solution is rapidly cooled by cold water or ice water and vigorously stirred, crystals with very small particles can be obtained; the other is to let the hot solution stand at room temperature to cool slowly, and then a uniform and larger product can be obtained. [0003] The existing technology discloses some invention patents on the crystallization method for biomedicine preparation. The Chinese patent application number is CN201922322976.1, which discloses a crystall...
