This disclosure relates to a composition for use as an additive for fuels and lubricants including a reductive amination product of a vinyl terminated macromonomer (VTM) based aldehyde. Optionally aldehyde is reacted with the amino compound under condensation conditions sufficient to give an imine intermediate, and the imine intermediate is reacted under hydrogenation conditions sufficient to give the composition. The aldehyde is formed by reacting a VTM under hydroformylation conditions sufficient to form the aldehyde. A reductive amination method for making a composition for use as an additive for fuels and lubricants. The method includes reacting a VTM based aldehyde with an amino compound containing at least one —NH— group under condensation conditions sufficient to give an imine intermediate, and reacting the imine intermediate under hydrogenation conditions sufficient to give said composition. The aldehyde is formed by reacting a VTM under hydroformylation conditions sufficient to form the aldehyde.
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.
ADDITION D'ORGANOCUPRATES AUX OXAZOLIDINES CHIRALES α-β ETHYLENIQUES : I - RESULTATS - EFFETS DE SEL ET DE SOLVANT

Organocuprates add quantitatively to oxazolidines I.The steric course of the reaction can be reversed and the diastereoselectivity enhanced by salt effect and (or) by solvent effect.
