      EDTA disodium salt - a question  Bookmark   

Oh ye, my beeloved brethren!

There's a question - alas, as yet purely theoretical - that confuses SWIM's mind lately. Namely, he has some photographic product that is called EDTA disodium salt.

Can it bee used as a substitute for plain EDTA (for Knoevenagel condensation of p-dMeO-BA w/MeNO2) hoping that acetic acid would convert it to free acid anyway?

Or would it bee more wise to convert it to its free form first - but how? SWIM would imagine that EDTA is pretty water-soluble. Can it bee xtracted w/a non-polar or isolated in some other way?

Can it bee air-dried? is it stable to air?

Thank ye in advance for all yer input,

Methinks that you are confusing EDA (ethylenediamine) which can be used as the Knoevenagel condensation catalyst and EDTA (ethylenediamine tetraacetic acid) which cannot.

Yep, Terbium, you're right - a pure brainfart on my behalfblushblushblush

Ethylenediamine diacetate, not ethylenediammonium tetraacetic acidfrown

Not a slightest resemblance or hope to convert between the twofrown Sorry...
