Why do materials with salt tend to cause material flooding (boiling)?

Methyl benzoylbenzoate, which we have contaminated and cannot be used to produce finished products, is converted back into the recyclable raw material benzoylbenzoic acid through reduced washing and hydrolysis, followed by acid extraction. When this material is used in production, the presence of salts causes it to boil easily when heated (even with a slight increase in temperature). What is the reason? Thank you
It’s not because of the salt, but because the liquid phase contains methanol, which has a low boiling point and thus boils more easily.

The material we recycle has had its initial fraction (above 90 degrees) distilled off before acid extraction. Where does methanol come from?
There should be substances that are easy to vaporize.
:Lol, I don’t know if you’ve done concentration before – saltwater has that problem: it boils over easily, causing the material to spray everywhere. It’s all due to the salt content
:(My understanding is that the temperature difference among the components in your material is too large, preventing uniform boiling; once the temperature exceeds a certain level, explosive boiling can easily occur.) . . I’m not sure if it’s correct;P
During heating, saline solutions are prone to bumping due to uneven density.
That is because in a salt-containing solution, the density of the liquid at the bottom is greater than that of the liquid in the upper layers; this density variation leads to boiling over.
