I need to dissolve EDTA in a non-aqueous solution. I tried to follow a protocol described in: Scott et al., 1978, "Demineralization in Organic Solvents by Alkylammonium Salts of Ethylenediaminetetra-acetic Acid", Biochem. J., 169, 697-701.
In the paper the authors describe how to obtain an EDTA-ethanol solution by adding triethylamine dropwise. However, I could not reproduce this. I did achieve dissolution but only after adding triethylamine in very large amounts (about 50% of the ethanol volume).
Any ideas why I am not being able to reproduce the obtained results?
Any suggestions on alternative methods to achieve an EDTA solution using an organic solvent (e.g. ethanol)?
Thanks for your *delete me*
