Nitrate Solutions

The distribution coefficients of aniline between n-heptane and aqueous sodium nitrate solutions were measured at different temperatures. The activity coefficients of aniline in aqueous sodium nitrate solutions were determined. The effect of sodium nitrate on the dissociation of the anilinium ion was studied at different temperatures by a modified distribution method. Attention was directed to the choice of the extracting solvent and of the analytical method. The effect of the presence of undissociated anilinium ions on the distribution coefficients was taken into consideration.K0, Kb, ΔH, ΔF, and ΔS for the dissociation of the anilinium ion were evaluated.

Conventional Solvent Extraction

A new simple and fast analytical method was developed to characterize the content of lipids and fatty acids in bread. First, fatty acids were determined by gas chromatography and then the content of lipids was calculated by using a conversion factor. This method gave very accurate results; it was three times faster than the conventional solvent extraction method and its consumption of solvent was much lower. The high sensitivity allowed the distribution of lipids in bread to be determined.
