What should be noted? Reaction crystallization is mainly to achieve the purpose of purification of materials, need to use the reaction crystallizer. The reaction crystallization process refers to the process of chemical reaction between gas and liquid or liquid and liquid, which produces insoluble or insoluble solids.
Therefore, the reaction crystallizer can be used to separate some easily precipitated substances from other compounds.
Characteristics of the reaction Crystallizer: In practical use, the reaction Crystallizer shows a lot of advantages, first of all, its internal temperature and solution ph value are easy to control. and the overall structure of the equipment is relatively simple, use of low energy consumption. and the resulting crystal particle size distribution uniformity, can be required to produce high purity of the large crystal, grain uniformity easy filtration, the product quality is a great improvement.
In a word, the reaction crystallization process is characterized by high selectivity and is often used for separation and purification of products.
In order to better use the reaction Crystallizer, as a user, we need to pay attention to some problems, the main contents are as follows:
Precautions for use of reaction crystallizer 1, in order to reduce the phenomenon of wall, so the reaction mold wall and the guide tube part should be polished treatment, can also be configured crystal elimination device.
The upper fine crystal enters into the fine crystal elimination device and becomes the supersaturated back Crystallizer to continue crystallization.
2, to further improve the proportion of large crystals produced, can be installed in the lower part of the reaction crystallizer washing legs.
3, if necessary, can also set the crystal Seed Add, add crystal species to further improve product size distribution. 4, the use of the reaction Crystallizer, the user can also adjust the crystallization temperature according to the need, generally according to the best reaction rate to set.
