On the solubility of sodium acetate in ethyl acetate
The dissolution of the male substance is related to the physical properties and the environment. Sodium acetate is an organic salt, which is ionic; ethyl acetate is an organic ester, which is neutral. The difference between the two is quite obvious.
In common sense, ionic compounds are mostly soluble in polar solvents, because they can form strong interactions between ions and polar solvent molecules, such as soluble salts of water. And ethyl acetate, although it contains carbonyl groups, has a weak overall polarity and is a weak polar organic solvent.
Sodium acetate in ethyl acetate, the interaction between ions and weakly polar ethyl acetate molecules is weak, which is difficult to overcome the lattice energy of sodium acetate. Therefore, the solubility of sodium acetate in ethyl acetate is very small.
To increase its solubility, or to change the environmental conditions. When heating up, the molecular thermal motion intensifies, or some sodium acetate ions can break free from the lattice binding and enter ethyl acetate, and the solubility may be slightly increased. However, the boiling point of ethyl acetate is limited, and the temperature increase is limited.
Or add additives. If there is an amphiphilic substance, one end is pro-sodium acetate ion, and the other end is pro-ethyl acetate, or it can promote the affinity of the two, and increase the solubility of sodium acetate to ethyl acetate. However, the choice of this additive needs to be carefully considered to avoid the risk of impurities.
In short, the solubility of sodium acetate to ethyl acetate is naturally small. To change this situation, it is necessary to weigh various factors and operate cautiously.
