Reactive crystallization introduction
Reaction crystallization refers to the chemical reaction between a gas and a liquid or liquid or liquid to produce insoluble or insoluble solid matter. Reactive crystallization can make some substances that precipitate easily separate from other compounds, so as to achieve the purpose of purification. The reaction crystallization process is characterized by high selectivity and is often used in the separation and purification of products.
Several influencing factors of reactive crystallization
The degree of saturation, temperature, mixing uniformity, agitation strength and material purity.
Degree of saturation, temperature, mixing uniformity, agitation strength, and material purity.
Reactive crystallization advantages
The ordinary crystallization tank is poor in automation, and when the two phase or multiphase materials are mixed, ,the stirring process can be strong and easily producing a lot of fine grains In order to achieve good mixing effect . When the fine grain is less than 1 m, the fine grain will reunion and the Van der Waals force will come into effect. Therefore, when the product size distribution is too wide, the viscosity becomes larger, the washing capacity increases, and the residual liquid content between the crystals increases relatively after centrifugation, the low purity of the product will be caused. In addition, the operation is controlled by experience and simple indicators, so that there are differences in the operation of workers in different shifts. The difficulty to solve problems by workshop management results in large differences among the products, uneven distribution of grain size, and unstable quality of products. Considering the comprehensive cost, the intermittent operation is tedious, the power consumption is high, and it is not suitable for the production of mass products.
The reaction crystallization equipment can completely solve the above problems, and the product quality has reached the foreign advanced standards. The reaction crystallization is a complex process of heat and mass transfer. In different physical and chemical environments, the control steps of the crystallization process may change and reflect different behaviors. Especially for the pharmaceutical crystallization products, they have strict requirements on the crystal type, and also on the particle size distribution of the products, which directly affects the quality of drugs.
