cf. CA 55, 12157e. Mixtures of alkyl phenols (I) were obtained by alkylation of the phenols with isobutylene or diisobutylene. Monohydric I were separated and identified by paper chromatog. in solvent systems including HCONMe2/C6H14 or paraffin oil/MeOH/H2O. HCONH2-impregnated paper and the solvent system C6H6/CHCl3 are recommended for separating alkyl derivatives of pyrocatechols. For anal. purposes, the pyrocatechol derivatives can also be separated on polyamide powder columns with aqueous alc. as eluent. I and alkylcresols are also separated and identified by gas chromatog. on a nonpolar (silicone oil) and a polar (Polydiol 400 3,5-dinitrobenzoate) liquid phase. Rf values in 6 solvent systems and colors with o-chloro-p-nitroaniline (before and after spraying with O.1N NaOH) and diazotized sulfanilic acid are tabulated for PhOH and 25 I. Rf values are also tabulated for pyrocatechol and 4 alkylated derivatives in 3 solvent systems. Retention volumes are given for PhOH and 15 I.
