Interactions between volatiles and lipids in complex systems

1998

Partition equilibria of three aroma compounds in three different biphasic systems were studied by a liquid/liquid partition technique to investigate interactions that occur between volatiles and lipids in biphasic solutions. The lipids used were linoleic acid and ricinoleic acid and tetradecane as a model. The three aroma compounds were ethyl acetate, 2,5-dimethylpyrazine, and oct-1-en-3-ol. The results showed that the intermolecular forces involved were weak. Infrared spectroscopy was then performed on binary systems (tetradecane and linoleic acid or aroma compound) and on ternary systems (tetradecane, linoleic acid, and aroma compound) to determine the nature of the interactions. This met…

Gas—liquid chromatographic analyses

1984

Abstract The gas chromatography (GC) of n -alkyl acetates (CH 3 COOR), chloroacetates (CH 2 ClCOOR), dichloroacetates (CHCl 2 COOR) and trichloroacetates (CCl 3 COOR), where the alcohol chain length (R) varied between 1 and 8, and certain of their monochlorinated derivatives, 176 compounds altogether, has been studied on SE-30 and OV-351 glass capillary columns under the same operating conditions. The isomeric monochlorinated esters are eluted in direct order from the 1- chloro to the ω-chloro isomer, the separation of the isomers being complete on OV- 351. On SE-30, however, the peaks of the 6- and 7-chlorooctyl esters are partly overlapped. The separation of the mixtures of odd- and e…

Mass transfer in nonisothermal ferrocolloids under the effect of a magnetic field

1999

Abstract The paper presents a review of newest experimental results on particle thermal diffusion in hydrocarbon based ferrofluids. The measurements are performed using a vertical thermal diffusion column, the Soret coefficient is evaluated from particle separation curves employing a simple column theory which accounts for thermal convection in the vertical channel forced by a concentration buoyancy force arising during the thermophoretic transfer of heavy particles. High positive values of the Soret coefficient of lyophilized Fe 3 O 4 and Mn x Zn 1− x Fe 2 O 4 particles in surfacted tetradecane based colloids are measured. Experiments confirm the theoretically predicted anisotropy of parti…

Two polymorphs Ni(II) complexes containing the dicyanamide ligand: syntheses, structures and magnetic properties of {[Ni(meso-CTH)(μ1,5-dca)]ClO4}n a…

2004

Abstract Two polymorphs Ni(II) complexes {[Ni(meso-CTH)(μ1,5-dca)]ClO4}n (1) and [Ni(meso-CTH)][Ni(meso-CTH)(dca)2](ClO4)2 (2) have been obtained in the same synthesis from dicyanamide (dca) and [Ni(meso-CTH)](ClO4)2 and have been characterized by X-ray crystallography and magnetic measurements. Complex 1 is a 1D cationic polymeric zig-zag chain with single end-to-end dca bridges connecting Ni(II) ions in trans positions, whereas in compound 2 coexist two different types of Ni(II) mononuclear units, cationic square-planar and neutral octahedral. Variable-temperature magnetic measurements reveal weak ferromagnetic interactions across the single end-to-end dca bridges in 1, while for 2 the ma…
