摘要：

Gel-permeation chromatography is recognized as the most reliable method for the purification of aqueous solutions of the ligand tris(sodium-m-sulfonatophenyl)phosphane (TPPTS) and its industrially important rhodium complex derivatives (hydroformylation; Rhône-Poulenc/Ruhrchemie process). This purification technique has been modified for compounds of this type (air-exclusion) and has been optimized. In particular, the synthesis of spectroscopically and analytically pure TPPTS complexes since the synthesis of this ligand by E.G. Kuntz in 1975 has now been achieved for the first time. Sephadex-type gels and Fractogel HW-40F have proved to be the most effective stationary media. The outstanding utility of the method is exemplified by the easy accesibility of TPPTS rhodium(I) complexes which are ideal for hydroformylations in two-phase systems. © 1990.
