EA neutralisation question

[Bruce_Willis]

So when it comes to cleaning the used Ethyl Acetate I've been doing the shake method then followed by the salt water/brine wash.
After doing this and decanting to leave the brine behind, do I then need to do a freezer rest to remove any water that's now in the EA to return it back to its original water content? (or close to it as possible)
Does the brine step add more water to the EA?
I tried to go the mag stir route but when I added the sodium carbonate it clumped up around the stir bar and stopped it spinning no matter how high I cranked it up.

Saturated brine should pull a bit of water out of the EA, but it won't pull all of it due to equilibrium effects. A fridge rest of the EA should get it to a desirable moisture content, from what I gather.

Did you use anhydrous sodium carbonate?

Ok cheers for the reply. Not sure, the washing soda just states sodium carbonate with no other details.

Hydrated washing soda tends to be sort of greasy, translucent crystals, while the anhydrous stuff comes as a fine white powder, ime.

yeah it's definitely a fine white powder
