A paper chromatography of alcohols was devised. A solution decanted from a wellshaken mixture of 0.5cc. of an alcohol, 0.1-0.4cc. of ether containing 20% of carbon disulfide, and 1g. of powdered potassium hydroxide, is evaporated to dryness and the residue wetted with a drop of water is spotted on the start line of a filter paper. This is developed with butanol saturated with 2% aqueous solution of potassium hydroxide or sodium carbonate, and the finished papergram is examined under an ultraviolet light or with the Grote's reagent. This method was found to be applicable to the detection of methanol in ethanol and wine.
