Mixtures homogeneous versus heterogeneous

Fig. 1 shows 1-octene conversion versus time for the homogeneous and heterogenized complex on supports ROX-0.8 and ROX-N for the last case, results in three consecutive reaction runs are included. Products are a mixture of linear (L) and branched (B) isomers of aldehydes. Selectivity at 2 and 7 h (expresed as L/B) is also included in the figure. In general, the curves present a shape with two steps with different rates. These data show that i) in the first step (faster), the linear aldehyde is mainly obtained. Increase of the branched product is related to the easy isomerization of 1-octene to 2-octene in these kinds of complexes mainly when the diene ligands are replaced by CO ii) the selectivity of these...
