Solubility of ammonia salts in solvents?


Hi everyone,

Does anyone know the solubility of Ammonium Carbonate, Ammonium Acetate, and Potassium Carbonate in methanol and ethanol?

I have been looking everywhere for days and cannot find a reliable source of this information.

Thank you!!

Not in the CRC Handbook?

Ammonium acetate is soluble in both, acc. Wiki. Potassium carbonate is not soluble in either.

Ammonium BiCarbonate is insoluble in methanol. At least according to Wiki.

I found the wikipedia entries already and I've found more than a few that are inaccurate, so I don't trust them.

I couldn't find these values in CRC, but I did have a bit of luck on some of the others, though I can't say for certain these are correct because I haven't been able to cross-reference them.

Ammonium acetate - ethanol: soluble; methanol: 6.2g/100mL
Potassium carbonate - ethanol: insoluble; methanol: 4.7g/100mL
Ammonium carbonate - ethanol: 2.1g/100mL

That leaves ammonium carbonate and methanol...

I have reason to suspect ammonium carbonate is soluble in methanol and if so, the solubility for ammonium bicarbonate doesn't help me.

I have the same dates about solubility:
ammonium carbonate - ethanol 2.68 g/100 g (http://chemister.ru/Database/properties-en.php?dbid=1&id...)
potassium carbonate - ethanol abs. - insoluble, methanol 6 g/100 g at 25 C (http://chemister.ru/Database/properties-en.php?dbid=1&id...)
