Kinetics of multi-step reactions including hydroformylation, aldol condensation and hydrogenation was carried out in a single pot for optimization of the reaction parameters for the synthesis of C-8 aldehydes and alcohol from propene using an eco-friendly multi-functional heterogenous catalyst system [HF/HT] where [HF]=rhodium complex. HRh(CO)(PPh3)(3) and [HT]=hydrotalcite, Mg1-xAlx(OH2)(x+)(CO32-)(x/n)center dot mH(2)O. The catalyst [HF/HT] was synthesized by impregnation of [HF] onto the surface of [HT]. In the typical catalytic experiments conducted in a 100 mL high pressure reactor under the employed reaction conditions: propene = 10 atm, CO = 5 atm, H-2 = 15 atm. [HF/HT] = 700 mg. HT/HF ratio = 7, Mg/Al molar ratio of [HT] = 3.5, aldol temperature = 250 C, reaction time = 12 h, agitation speed = 1000 rpm, and in 50 mL toluene as a solvent, 68.4 x 10(-3) M of 2-ethylhexanol with 18% selectivity was achieved. The rates of reactions were determined by analyzing the amounts of products formed at different time using gas chromatography. Kinetics of the various reactions were performed in detail by investigating the effect of reaction parameters such as Mg/Al molar ratio of [HT] at aldol temperature 150 and 250 C, amount of [HT] and [HF] complex, aldol temperature, partial pressure of CO and H-2 on the rates of formation of products namely, 2-ethylhexanol, 2-ethylhexanal, 2-ethylhexenal, butanals and butanols. The rates of reactions were found to be influenced by all these studied parameters. On increasing these parameters, the rates of formation of the products and their further conversion in single pot were favoured. (c) 2009 Elsevier B.V. All rights reserved.
