The capability of this system to catalyze the hydroformylation of hex-1-ene, cyclohexene, 2,3-dimethyl-but-1-ene and 2-methyl-pent-2-ene and their quaternary mixture (synthetic naphtha) has been demonstrated. This innovative method to perform the in situ hydroformylation of the olefins present in naphthas to oxygenated products would be a promissory work for a future industrial catalytic process applicable to gasoline improving based on oxo-reactions. An important observation is that variation of CO/H 2 pressure (6.8-34.0 atm), temperature (60-80 oC), reaction time (2-10 h), rhodium concentration ((1.0-1.8)x10 -3 mol/L) affect hydroformylation reaction rates. Optimal conversion to oxygenated products were achieved under Rh = 1.8 x10 -2 mol/L, P(CO/H 2) = 34 atm (CO/H 2 = 1:1) at 80 oC for 10 h.2010http://zaguan.unizar.es/record/4836410.2174/1876214X01003010044http://zaguan.unizar.es/record/48364oai:zaguan.unizar.es:48364info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2006-03973Open Catalysis Journal 3, 1 (2010), 44-49byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
