Abstract: The sample was treated with an excess of Ac2O in pyridine for 20 min. at room temp., and then analyzed at 140° on a column, 230 cm. long and 0.4 cm. diam., of 4% trixylenyl phosphate and 3% Bentone B-27 on Embacel pretreated with hexamethyldisilazane. The relative retention time increased in the order of phenol, 2-methylphenol, 4-methylphenol, 3-methylphenol, 2,6-dimethylphenol, 2,5-dimethylphenol, 2,4-dimethylphenol, 2,3-dimethylphenol, 3,5-dimethylphenol, and 3,4-dimethylphenol.
