Well the problem with simply mixing sulfuric acid and NaCl in IPA, is that a mole of water is formed for each mole of HCl generated. This water has to be removed somehow. Don't know if the formed NaHSO4 will soak it up sufficiently?
Otherwise, an alternative approach would be to do the reaction above, and dry the IPA over a proper amount of 3A molecular sieves.
Say for 1 L of 5N IPA, the following would be required:
1 L IPA
5 moles NaCl
5 moles H2SO4
Let it react, and decant the IPA, rinsing the sludge with a little more fresh IPA, to get a total volume of 1 L.
5 moles of water should be present here. This would require(assuming 20% wt% capacity of the sieves):
18g/mole * 5mole = 90 / 0.2 = 450 g's sieves (500 g's to be sure).
Sure is a lot of sieves to use, but the can of course be reused over and over to generate unlimited supplies of cheap dry HCl / IPA...
Comments?
