How to remove impurities in the product
The impurities of general chemicals are divided into homology and exogenous. Endogenous impurities are generally caused by side reactions. This impurities are regular and impurities are basically fixed.This impurity requires control process conditions to minimize side reactions to suppress.In addition, the solvent itself is also an endogenous impurities. Exogenous impurities are caused by environmental contact during the process of production, separation, and purification, including container, solvent, pipeline and other factors. Such impurities composition is difficult to control.control.
Heavy crystals are a good way to remove impurities, but high energy consumption, and the operating conditions are not so easy to control.

Is there any physical analysis of impurities?Consider the process of melting crystals.Specifically, the material still has twice heating after crystallization, which is slightly melting on the surface, so as to wash away impurities and enhance the purity of the product.

Good boss!The company sells: 2 methoxy-4 chloro-5 fluoropyradine (1801-06-5), 2.4 dichloropatradine (2927-71-1), 4.6 dichloropatradine (213265-83-9), 4.6 dichloropine (1193-21-1) The new production technology of the four pyrimidine products. Compared with the previous method of using metronoss-phosphorus, the advantage of our new process is: no pollution without three wastes, which can reduce the pollution that can reduce it, which can reduceThe production cost of the enterprise.If you are interested, you can talk about the window privately, talk about it in detail.In addition, it is also sold: Malayside (541-59-3), 2 amino-2 cyanocyanide (6719-21-7) two new product production technology, the production cost is as low as beyond your imagination, interested in your imagination, interestedYou can talk about \u0026 nbsp; \u0026 nbsp; look forward to your cooperation with you in detail.At the same time, our company also undertakes various technical problems and new processes on behalf of the technology. Welcome to inquire about QQ1020106663

4,6-dichloropyamididine conventional is obtained from 4,6-dihydroxyraine and chlorine chloride.The key is to consider the quality transmission reaction and reduce the side reaction.Then perform simple post -treatment

Do you need to know if the other impurities in your product are in front of the frozen crystals and are in it \u0026 nbsp; \u0026 nbsp; or have other impurities in the finished product?If you have \u0026 nbsp; \u0026 nbsp; you can consider evaporating

It is best to determine which type of substance is, and then determine which method is used.If the content is not high, you can consider using ion exchange resin to separate the separation. Of course, this process should be performed at a low concentration segment.Or try it with layer analysis technology.

The method of lazy people is 2 crystals, but the cost may not be able to stand.The solution on the second floor is the fundamental method, but it is not estimated that it must be done with peace of mind.
The methods that can be considered are: 1. \u0026 nbsp; \u0026 nbsp; needle -shaped crystals are generally large, so impurities may be wrapped in crystals.It will be better to change from static crystals to dynamic crystals. 2. When centrifugal, you can use a solvent to wash the materials in the centrifugal machine, provided that it is allowed to do so.In this way, my experience (for my products) can increase the content of about 1% 3. Reduce the number of applications of the crystalline parent liquid.
