  • Patent number: 3981929
    Abstract: A method of separating methylolphenols from an organic solution containing the methylolphenols by contacting the organic solution with an aqueous alkaline borate solution in which lithium ions are present in a quantity greater than any other single alkali metal ion for a period of time sufficient to form a solid complex of the lithium and boron with the methylolphenols which then are separated from the organic solution.The methylolphenols subsequently may be recovered from the complex by decomposing the complex with acid and dissolving the released methylolphenols in an organic solvent.
