- 中文摘要: Paper chromatography using the polyamide impregnated paper were reviewed. The method for preparing plates coated with a thin-layer of polyamide for chromatographical work was devised. Circular polyamide plates for horizontal chromatography was also prepared. These plates were applied to the chromatography of the phenols, phenolic carboxylic acids and tropolones. The reproducibility of the chromatogram were excellent. It was found that polyamide thin-layer chromatography is the most convenient method for the separation of phenolic substances ever found. The Rf values of phenols, phenolic carboxylic acids and tropolones are tabulated and the relations between solvents, Rf values and structure of phenols are discussed.
