Why is it necessary to remove the crystals before the solvent has completely evaporated? In the recrystallization of benzil, why do you have to cool the ethanol solution of benzil slowly? Why do we use a minimum amount of solvent to dissolve the solid that is to be recrystallized?
In many cases, it definitely makes sense to prepare a bigger batch of diluted essential oil so you have it available. Also, several essential oil uses only require a bit of oil, which makes it impractical to make a single serving.
