What is concentrated crystallization and what is the difference between concentrated crystallization and cooling, evaporative crystallization?

The concentrated crystallization is to evaporate and concentrate the solvent and remove the solvent, so as to precipitate the solute crystal. Generally, we mean to use the rotary evaporator for concentration, or to use the vacuum desolvation in industry. The cooling crystallization is carried out through the temperature sensitivity to the solubility, which is not the same as the solvent volume.

To concentrate crystal is to evaporate and concentrate the solvent, to remove the solvent, so as to precipitate the solute crystal. Generally, we mean to use a rotary evaporator for concentration, or to use vacuum for dissolution in industry. To cool the crystallization is to crystallize through the sensitivity of temperature to solubility. This is not the same as the solvent volume.

What is recrystallization, cooling crystallization, evaporative crystallization

These several concepts are the difficulty of middle school, should pay attention to distinguish.
Recrystallization, that is, repeated crystallization, is a general term.
Cooling crystallization is a method of crystallization, i.e., heating to obtain a hot saturated solution, and then cooling. In the process of cooling, the solubility of solute decreases, so the crystallization precipitates, which is generally applicable to the case where the solubility varies greatly with temperature, such as KNO3.
Evaporative crystallization, i.e. directly heating to evaporate the solvent to obtain solute crystals, is generally applicable to the matter with little change in solubility with temperature, and will not decompose stable properties during heating, such as NaCl.
