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, Antoncho |

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 behalf ![]() ![]() ![]() Ethylenediamine diacetate, not ethylenediammonium tetraacetic acid ![]() Not a slightest resemblance or hope to convert between the two ![]() Antoncho |
