The interaction of amino acids with ethoxylated stearic acid nonionic surfactants was studied by charge-transfer reversed-phase thin-layer chromatography and the relative strength of interaction was calculated. In the majority of cases the surfactant has a negligible effect on the hydrophobicity of

## Abstract Stearolic acid (2) was prepared from oleic acid (1) and converted to 4, 5, and 7 by way of the „acetylene zipper”︁ reaction. Compounds 5 and 7 were transformed to the (ω – 1) ketones 8 and 9 and dimerized by way of the Glaser coupling reaction to 11 and 12. At daylight, 12 polymerizes t

The C-D stretching regions of the infrared and Raman spectra of 14 different palmitic and stearic acids containing isolated CD 2 groups are reported. Anomalous behaviour is observed when substitution occurs near the terminal methyl group, which behaviour can not be explained in terms of crystal fiel

All the cis octadecenoic esters have been converted to cyclopropane compounds by reaction with zinc-copper couple and di-iodomethane. Their gas-liquid chromatographic behaviour on four liquid phases is described. Six isomers (2,3-; 3,4-; 4,5-; 15,16-; 16,17 -; and 17,18 -) have distinctive nuclear m
