## Abstract The solvation parameter model is used to characterize the separation properties of the polar stationary phases EC‐Wax and PAG with a poly(ethylene oxide) backbone (substituted with propylene oxide in the case of PAG) and the cyanopropyl‐substituted polysilphenylene–siloxane stationary p
Due to the extreme complexity of oils such as animal tallows, determination of fatty acid composition by direct gas chromatographic examination of their unfractionated methyl esters is of limited utility. A more detailed analysis of animal fats has been achieved using a silicic acid column chromatog
Addition of Yb(fod)3 to methyl oleate (cis) and methyl elaidate (trans) shifts the carboxylic lines of their ~3C-NMR spectra to different extents; that of the cis isomer less than that of the trans isomer, as is to be expected. On the same theoretical ground it can be anticipated that the opposite
