Compound: Tris(3,5-bis(trifluoromethyl)phenyl)phosphine, is researched, Molecular C24H9F18P, CAS is 175136-62-6, about Full kinetic description of 1-octene hydroformylation in a supercritical medium, the main research direction is full kinetic model octene hydroformylation supercritical.Application of 175136-62-6.
The kinetics of the hydroformylation of 1-octene in a supercritical carbon dioxide medium, catalyzed by a tris(3,5-bis[trifluoromethyl]phenyl)phosphine-modified rhodium catalyst, were studied. The influence of the concentration of carbon dioxide, reactants, catalyst precursors, and the reaction temperature was determined A kinetic model was developed, which describes the concentration-time profiles of the reactants, the linear and branched aldehydes, and the internal alkenes. Using the kinetic model activation energies for hydroformylation of 1-octene to nonanal and 2-methyloctanal were determined Throughout the concentration ranges studied an approx. first order dependence of the hydroformylation rate on the hydrogen and catalyst concentration was found which indicated that oxidative addition of hydrogen was the rate limiting step. The increase in reaction rate and regioselectivity with an increase in ligand concentration is a striking feature of the catalyst studied here. At higher concentrations the reaction rate has a strong neg. order dependence on the carbon monoxide concentration The reaction rate had a pos. order in 1-octene at a concentration <0.5 mol L-1 while saturation kinetics were observed at a higher concentration The results were explained by invoking the contribution of both monophosphine and diphosphine rhodium species to the hydroformylation catalysis. After consulting a lot of data, we found that this compound(175136-62-6)Application of 175136-62-6 can be used in many types of reactions. And in most cases, this compound has more advantages.
