Nickel Acetate (tetrahydrate vs anhydrous)

overunity33 - 11-4-2010 at 15:44

I am trying to perform a reaction that calls for Nickel Acetate. It is added to a solution of xylene. I am using anhydrous nickel acetate and it will not dissolve in the xylene. Is it possible to convert anhydrous to the tetrahydrate form just by leaving it in a humid environment? MSDS's say that the anhydrous form is only water soluble while the tetrahydrate form will dissolve in xylene. Any suggestions? Thanks.

Just crystalize your nickel acetate from water, to obtain hydrated salt.

Duh, thanks so much I can't believe I hadn't thought of that.

I seriously question the solubility you mentioned above. That's contrary to every other salt I know of if it's correct. Are you sure you're not after trimeric nickel(II) acetylacetonate; [Ni(acac)2]3, which is soluble in benzene and other aromatic hydrocarbon solvents.
