The aim of the presented research was to compare the chromatographic separation process, a mixture of food dyes obtained in capillary action liquid chromatography (caLC) columns packed with adsorbent type RP-8 and RP-18 and using as the eluent: methanol-water-acetic acid (4:5:1, v/v). The obtained retention data were compared with separation in caLC columns with different internal diameters, different distance of migration and the different mode of development the chromatograms.

Abstract (-)D-and (+)D-4-methoxyphenylmethyl-thiophosphinic acid, quinine salts of (-)D-and (+)D-4-methoxyphenylmethylthiophosphinic acid, checking of resolution by 31P{ 1H} NMR-spectroscopy (-)D-and(+)D-4-CH3OC6H4(CH3)P(S)OH acid were obtained from fractional crystallization of the quinine salt of the racemic acid. 31P{1H} NMR spectroscopy proved to be very useful in checking the separation process as well as the optical purity of the diastereomers and enan­tiomers.
