Multifactorial analysis in the study of hydroformylation of oct-1-ene using supported aqueous phase catalysis

The influence of the hydration and the surface characteristics of five supp orts in the hydroformylation of oct-l-ene by supported aqueous phase cataly sis (SAPC) using [Rh-2(mu -(SBu)-Bu-t)(2)(CO)(2) (TPPTS)(2)] as catalyst wa s studied. The results confirm that the size of the pores and the amounts o f water were found to be the determining factors contributing to the SAPC. According to the size of pores there is a critical value for which the SAPC takes place either in the classical model or in conditions where the pores are filled. When the pores are fully filled the SAPC can operate efficient ly onto the external surface, stabilising the conversion in a relatively wi de range of support hydration.
