Vapor Pressures, Liquid Densities, Liquid Heat Capacities, and Ideal Gas Thermodynamic Properties for 3-Methylhexanal and 3,4-Dimethylpentanal

Vapor pressures, liquid densities, and liquid heat capacities were measured for 3-methylhexanal and 3,4-dimethylpentanal which are two of several C7 aldehyde reaction products that can be obtained from the hydroformylation of hexenes using cobalt or rhodium homogeneous catalyst precursors.The vapor pressure data were fitted to the Miller and Antoine equations and also compared to predictions obtained form the Riedel-Plank-Miller equation.Values for the critical temperature and critical pressure were derived by group contribution methods and compared to independent values obtained by fitting the vapor pressure data to the Riedel-Plank-Miller equation and two corresponding-states-based equations.The liquid density data were compared to predictions obtained from the Yen-Woods equation and were also fitted to an empirical equation.Predictions from the Sternling-Brown, Yuan and Stiel, and the Rowlinson corresponding-state correlations were in good agreement with the liquid heat capacity data, although an empirical polynomial equation was also tested and had a lower mean deviation.Ideal gas thermodynamic properties were also derived and were used to calculate some of the predicted quantities.

Dual Rh?Ru Catalysts for Reductive Hydroformylation of Olefins to Alcohols

An active and selective dual catalytic system to promote domino hydroformylation–reduction reactions is described. Apart from terminal, di- and trisubstituted olefins, for the first time the less active internal C?C double bond of tetrasubstituted alkenes can also be utilized. As an example, 2,3-dimethylbut-2-ene is converted into the corresponding n-alcohol with high yield (90 %) as well as regio- and chemoselectivity (>97 %). Key for this development is the use of a combination of Rh complexes with bulky monophosphite ligands and the Ru-based Shvo's complex. A variety of aromatic and aliphatic alkenes can be directly used to obtain mainly linear alcohols.
