Does Ethanole react with NaClO3-solution ?


Recently I had the idea of salting out chlorate/chloride-brine by just adding ethanole ...
==> Would the ethanole be inert ? (or would it be a dangerous idea ?)

================

If this were allowable it could have several benefits:
==> quicker: No water would have to be boiled for leghts of time ...
==> fine crystal-powder instead of rougher grains from evaporation ...

Maybe even a fractioning could be achieved: Possibly either the NaCl or the NaClO3 would be enriched in the salt ...

How about the idea ?

It's a fuel and oxidizer mixture, so the ethanol is not going to be "inert". But sodium chlorate doesn't readily react with ethanol. There is a patent somewhere that uses acetone to dissolve and separate solid calcium chlorate from the therein insoluble CaCl2. Then separates by distilling the acetone. I would be cautious with distilling the ethanol out and use a waterbath, since it needs a higher temperature.

Another idea to extract the NaClO3. Muck in DE25785 evaporates the solution mixture of NaCl and NaClO3, then treats the residue with hot saturated NaCl solution to extract the NaClO3 (the hot NaCl solubilizes NaClO3, which is then said to crystallize on cooling when saturated enough).

Simply boil down the solution. The NaCl will precipate first. You need to filter the solution boling hot. I did this several times using a heat gun to keep the Buchner filter hot. NaClO3 will then crystallize from the filtrate upon cooling.

Interesting...
So it won't do anything...
But if it does, you get acetic acid...
Then pH drops and you're fucked.

Could be fun to watch though. From a safe distance.

Fortunately, sodium chlorate is fairly inert at neutral pH, so I wouldn't be too terrified of doing this, as long as you have a buffer to keep it stable. You could add some powdered CaCO3, for instance.
