Hi all, I am not sure if I should post this question here or not. But since I am a inorganic student, I decide to post it here. I made my compound(ligand) which is water soluble and also soluble in MeOH, CHCl3,...etc. But I also have side product, LiOH, produced from the reaction. I want to separate my compound(ligand) from the mixture. I am not sure if LiOH is soluble in CHCl3, acetone. Or it has tiny solubility in these.(I heard from some people LiOH has some solubility in CHCl3 or acetone, although I am not sure.) Because if LiOH is not soluble in CHCl3 or say acetone, I can extract my compound from CHCl3. Please solve this question for me. Thank you very much.

Do you have a bottle of LiOH on the inorganic shelf in lab?  you could put some CHCl3 in a vial and add LiOH slowly to see if it dissolves.

From the Merck Index:

...
Properties: Small monoclinic crystals. d420 1.51. Heat of formation -188.9 kcal/mol at 25°. Heat of soln -0.87 kcal/mol at 25°. Soly in water (w/w) at 0°: 10.7%; at 20°: 10.9%; at 100°: 14.8%. Slightly sol in alcohol. pH of a 1.0N soln about 14.
Caution: Strongly alkaline and hence caustic. Very irritating to skin. Systemic toxicity similar to other lithium compds. See Lithium

There is no LiOH in my lab and I did try NaOH in CHCl3. However, it is very hard to tell if there is any dissolved or not.
