Non-aqueous ionogenic ligand liquid has a quaternary ammonium and/or phosphonium cation and triarylphosphine anion and up to 5 equivalents excess of the amine and/or phosphine from which the cation is derived or of an alkali(ne earth) salt of the anion. Non-aqueous ionogenic ligand liquid is of formula (Q<+>)aAa- (I) and has a quaternary ammonium or phosphonium cation and triarylphosphine anion and up to 5 equivalents excess of (i) the amine and/or phosphine from which the cation is derived or (ii) an alkali(ne earth) salt of the triarylphosphine anion. Q<+> = quaternary ammonium and/or phosphonium cation with a single charge or the equivalent of an ammonium and/or phosphonium ion with a multiple charge; Aa- = triarylphosphine of formula (II); Ar1, Ar2, Ar3 = 6-14 carbon (C) aryl; Y1, Y2, Y3 = 1-4 C alkyl or alkoxy, chlorine, bromine, hydroxyl, cyanide, nitro or an amino group of the formula NR<1>R<2>; R<1>, R<2> = hydrogen or 1-4 C alkyl; m1, m2, m3 = 0-5; n1, n2, n3 = 0-3; at least one of n1, n2, n3 = 1 or more; a = n1 + n2 + n3. An Independent claim is also included for the preparation of the ligand liquid by reacting a solution of the amine and/or phosphine from which Q<+> is derived with an acid and/or alkylating agent in the presence of an aqueous solution of the alkali(ne earth) salt(s) of the triarylphosphine Aa-. |
