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,
Antoncho
