Known mixtures of fatty alcohol acetates were separated into the saturated, monoenoic, dienoic and trienoic components by the thin-layer chromatography using mercuric acetate adduct method and silver nitrate-silicic acid method. Sample alcohol acetates were as follows; 1. Steary 1 alcohol acetate. 2. Oleyl alcohol acetate. 3. Linoleyl alcohol acetate. 4. Linolenyl alcohol acetate. 5. Docosenyl alcohol acetate. 6. Sperm whale alcohol acetate. 7. Fin whale alcohol acetates, cow milk alcohol acetates, shark liver alcohol acetates. Three alcohols of No. 7 were prepared from fin whale oil, cow milk fat and shark liver oil by the reduction method with lithium aluminum hydride. Petroleum ether : ethyl ether (80 : 20 vol/vol) was better developer than other solvents in the case by silver nitrate-silicic acid method. n-Propyl alcohol : acetic acid : pyridine (150 : 1 : 1 vol/vol/vol), diisobutyl ketone : acetic acid (40 : 10 vol/vol) were better developers in the case by mercuric acetate adduct method. Silica gel G was a suitable adsorbent in this experiment. Monoenoic, dienoic and trienoic fatty alcohols thus showed fine separation on the thin-layer chro-matography.
