Hi, I have to separate a mixture of the following sorts of components;

 

Methacrylic Acid ()

Methanol (CH3OH)

Ammonium Bisulphate ((NH4)HSO4)

Sulphuric Acid (H2SO4)

Water (H2O)

Acetone disulfonic acid (C3H6O7S2)

 

The mixture is to be sent to a furnace, where SO2 should be produced as a feed to the contact process.

I was thinking that it would be advantageous to separate the water, ammonium bisulphate and acetone disulfonic acid rather than send it to the furnace, and use it to produce other products as the thermal decomposition of (NH4)HSO4 would produce nitrous oxides, which would be a problem.

 

I can't find much data on the acetone disulfonic acid or the ammonium bisulphate, but to my understanding they would be dissolved in the water, so I can't think of any properties to base separation methods around.

 

Can anyone suggest any methods to separate these components? 

Kind Regards

Hi ,

What is hapening if you decrease the temperature of the mixture ? You may recover some solid salt ?

my 2 cents.

Hi, could you please elaborate on this, thanks.

 

I also read that if I was to send it to an evaporator, that would mean that the water and methanol would be removed, and I also read that the crystalline solids (ammonium bisulphate and acetone disulphonic acid) would precipitate out of the solution. Is this possible?

Hi,

Yes , it's a matter of solubility , either you drop the temperature or you concentrate the solid by evaporation of the solvant .

Let you try in the lab
