I searched for the solubility of oxalic acid on the internet and found this:

1. An organic chemistry lab book gives the following solubility data for oxalic acid (IUPAC name - ethanedioic acid)
9.5 g/100mL of water 23.7 g/100 mL of ethanol 16.9 g/100 mL of etherIt is nice to see that oxalic acid dissolves in ethanol, but for setting up some Mannich reaction procedure, I 'd like to know if these figures are accurate.
I found this in some basic organic chemistry textbook (Morrison & Boyd, 6th ed., Organic chemistry p 742), which has a funny cartoon on page 474.
It goes like this: Donnald duck walks towards his lab table saying: 'If I mix CH
2 (edit: methylene, formed by the ultraviolet light photolysis of diazomethane ) with NH
4 and boil the atoms in osmotic fog, I should get speckled nitrogen'. At the same time his 3 nephews are saying each seperately:
* He 's talking chemical talk !
* But he knows nothing
* about chemicals !
Anyway, the book says (p 742) that the solubility of oxalic acid is 9 g / 100 g H
2O at 20 °C.
Could someone give me an accurate figure of the solubility of oxalic acid in ethanol (this is my primary interest, because a solution of formaldehyde / amine / ethanol is going to bee dropped slowely into an ethanolic solution of ketone and oxalic acid).
