May I ask organic solvent that can dissolve EDTA or its second sodium salt

Ethylemines and hydrophilicism are all possible. I tried it, you can try it.

I use EDTA's flowing phase, I don't know if it has a significance to you
flowing phase: acetyol: methanol: modified agent \u003d 2: 3.5: 4
Modified agent: 1.5Gedta-K2, sodium 15g acetate, sodium, 15g acetate, and sodium, 15g acetate,, 15g acetate, sodium, 15g acetate, and sodium 15g.1.0g of silicone powder, placed in 500ml of water, stirred it in full, and settled overnight (12HOURS), filtering the filtering solution as a modified agent.

Can ethylamine and formaldehyde can consider whether I can inspire some of the synthesis methods of EDTA and hope that I can attract jade instead of bricks.

Extradeomal, such as formaldehyde, should be okay

Find an organic monopoly ammonium salt, that is, ionic liquid.EssenceEssenceEssenceEssence

Use the principle of similar compatibility, find it, select reagents from the process of synthesis
