Hi There,
I am looking for a proper method to purify some iron complexes from triethylammonium chloride which forms during the reaction. Could anyone advise, please? Recrystallization a few times from acetone was not sufficient.
Thanks
It is quite difficult to give an answer, as thze nature of you complex was not disclosed.
triethylammonium chloride solubility:
chloroform: very soluble [Ref.] ethanol: very soluble [Ref.]
Maybe you complex is not soluble in this solvents!
Thanks for your answer. The complexes are neutral iron complexe with tetradentate ligands. Almost soluble in every solvent and presumably reactive to water.
Dear Monther Zreid some questions remain: Did you follow a literature procedure? If yes, what is said about the purification of your complex? When you say that it is "presumably reactive to water", how do you know this? I would e.g. try to dissolve your product in a minimum amount of acetone and precipitate your iron complex with diethyl ether or n-pentane.
Sir, you have to boil the complex in ammonia solution preferably 28 to 30 % ammonia content. On heating the complex in ammonia solution you will be left with brown precipitate, heating should commence for a period of 30 to 45 min @ 200 deg. C. After that carefully cool down the solution and filter it through whatman filter paper no 42, wash it thoroughly with cold water. The brown precipitate is your Iron.
