Does anyone know of an appropriate solvent to dissolve magnesium oleate?
I have tried searching the literature and I am seeing that the salt is insoluble in many solvents. I have tried water, ethanol, pyridine, acetonitrile, methylene chloride, hexanes, and acetic acid. Among all these solvents, acetic acid did the trick--however, I do not want to alter the chemistry of the compound and strip the magnesium off the oleate.
A manufacturer reports that magnesium stearate is insoluble in diethyl ether, water, and alcohol. I am looking for more opinions on this issue since I wish to solubilize this compound for analyses via tandem mass spectrometry and development of an assay for characterization of lipids.
Thanks.
Good day, Rayan Murtada! Hope you are doing well.
In 1938, guys possibly dissolved anhydrous magnesium oleate in cold dry benzene:

"The remainder was refluxed with benzene for 20 minutes, and the clear yellow supernatant layer was decanted while still hot and evaporated to dryness. The residue was crystallised from benzene. It was a yellow glassy material which dissolved readily in cold dry benzene."
Best of luck in your research!
