Crystallization process of azelaic acid
Thread Content
For the crystallization of dibasic acids, using my friend’s pilot-scale equipment, various adjustments were made to the crystallization equipment and processes, but with poor results; the current purity level is not high. The reactants are of good quality, so what is the problem?
Possible causes of the problem include inaccurate temperature control during the crystallization process, improper selection of solvent, or an overly fast cooling rate that leads to incomplete crystallization. It is recommended to optimize the crystallization process, such as adjusting the cooling rate, using more suitable solvents, or improving temperature control. It is also necessary to check for any vulnerabilities in the equipment to ensure that all devices are functioning properly. .
