    Abstract: The separation of phosphine oxides (I) and alkylarylphosphines (II) from an organic reaction mixture from homogeneous hydroformylation is carried out using a catalyst system of organometallic complex compounds and a molar excess of ammonium salts (III) of aromatic phosphines as ligand. The reaction mixture is extracted with a 0.01-0.5 wt.% alkali hydroxide solution, then the aqueous phase containing (I) and (II) is separated. (III) are e.g. alkyl- and/or arylammonium salts (IIIA) of sulphonated or carboxylated triarylphosphines or salts (IIIB) of amino-substituted triarylphosphines and organic carboxylic or sulphonic acids, etc;in which X, A, R = a sulphonate (SO3 ) or carboxylate (COO ) group or R = a phosphonate (PO3 ) or 2-aminoethane bisphosphonate Ä-NH-CH2-CH(PO3 )2Ü group; at least one of a , b, c = 1, the rest = 0 or 1, n = 1, 2 or 3; R , R - 4-30 carbon (C) alkyl or 6-10 C aryl or cycloalkyl and R may also = hydrogen (H); R = H or 1-12 C alkyl; R = 1-25 C alkyl or 6-10 C aryl; R = linear 1-8 C alkylene, 2-6 C alkylene with ether oxygen (O) in the chain, 3-10 C cycloalkylene or a group e.g. of formula (IVA); at least one of d, e, f, g, h, k, l, m, o, p = 1, the rest = 0 or 1; y = (d+e+f+g+h+k+l+m+o+p); x = 0 or 1; R , R = 4-26 C alkyl, benzyl or optionally substituted 6-10 C aryl or cycloalkyl and R may also = H; R = H or 1-12 C alkyl; R = linear 1-8 C alkylene, 2-4 C alkylene with ether O in the chain, 3-10 C cycloalkylene, (IVA; h = 0) or (IVB; e = 0); R = 1-25 C alkyl or 6-10 C aryl; q = 0 and r, s, t = 1; or q, r = 1 and s, t = 1 or 2; or, if R = (IVA) or (IVB), q = 1, r = 0 and s, t = 0 or 1.
