On the reasons why ethyl acetate is used as a good solvent for recrystallization
Those who recrystallize want to obtain pure matter. Choosing a good solvent is even more important. Ethyl acetate is a good choice for recrystallization, and there are various reasons.

First, its solubility is different. At high temperature, it has strong solubility to the object to be recrystallized, which can make the solute fully soluble. This is like melting snow in warm spring, and everything melts in the liquid. When it cools down, its solubility to the solute decreases sharply. The solute freezes in cold weather and precipitates from the solution. This property is just suitable for recrystallization to purify the solute.

Second, the boiling point of ethyl acetate is suitable. Moderate boiling point, so that when heating the concentrated solution, it will not overboil and decompose the solute, nor will it be difficult to control if the boiling point is too high. And when distillation is recovered, it is easy to operate and energy consumption is also saved, just like riding a horse and a cart, with a degree of urgency.

Furthermore, its chemical properties are stable. During the recrystallization process, it does not chemically react with the solute, just like a gentleman's friend, and it is different, without disturbing the nature of the solute, so as to maintain the integrity of its chemical structure.

In addition, ethyl acetate is less toxic, and it is quite harmless to the experimenter. And its smell is tolerable, unlike a foul-smelling agent, which is uncomfortable. In the experimental environment, it will not be too polluted, just like a breeze entering the room, refreshing and pleasant.

From this perspective, ethyl acetate, with its unique solubility, suitable boiling point, stable chemistry and low toxicity, is a good solvent for recrystallization, which is essential for the purification of substances.
