Abstract:
In a process for the removal of &bgr;-diketone byproducts from a reaction mixture containing a monovalent copper &bgr;-diketone complex product prepared by reacting a reactive copper compound with an H form or K form of a fluorinated &bgr;-diketone and, optionally, a stabilizing organic ligand (L), contaminated with the unreacted H form or K form fluorinated &bgr;-diketone and a divalent copper &bgr;-diketone complex byproduct, the improvement for removing the unreacted H form or K form fluorinated &bgr;-diketone from the reaction mixture which comprises:contacting the reaction mixture with an effective amount of double deionized water for solubilizing the H form or K form fluorinated &bgr;-diketone; forming an aqueous phase containing the H form or K form fluorinated &bgr;-diketone and an organic phase containing the monovalent copper &bgr;-diketone complex product; separating the aqueous phase from the organic phase; and, recovering the monovalent copper &bgr;-diketone complex product.
