Janak, J. published the artcileSeparation and analysis of dihydric phenols by gas chromatography, Recommanded Product: 4-(2,4,4-Trimethylpentan-2-yl)benzene-1,2-diol, the publication is Collection of Czechoslovak Chemical Communications (1959), 1960-6, database is CAplus.
Specific elution volumes (chromatographic spectra) of some dihydric phenols (pyrocatechol, 3-methyl-, 4-methyl-, 4-ethyl-, 4-tert-butyl-, 4-tert-octyl-, 3,4-dimethyl-, 3,5-dimethyl-, 4,5-dimethyl-, 3,5-di-tert-butylpyrocatechol, resorcinol, 4-ethylresorcinol, quinol, and ethylquinol) were determined on nonpolar (dimethyl polysiloxane) or (better) on polar stationary phases (mannitol at temperature 170-90°, dulcitol at 200°, inositol at 230-45°, and galactonic acid lactone at 190°). As the carrier, Celite C 545 was used. The relation between chem. structure of the (substituted) dihydric phenol and chromatographic behavior is discussed on the basis of the interaction with the stationary phase (H bonding). The method was applied for the analysis of raw pyrocatechol from Northern Bohemia brown coal tar used in the manufacture of tanning materials.
Collection of Czechoslovak Chemical Communications published new progress about 1139-46-4. 1139-46-4 belongs to alcohols-buliding-blocks, auxiliary class Benzene,Phenol, name is 4-(2,4,4-Trimethylpentan-2-yl)benzene-1,2-diol, and the molecular formula is C14H22O2, Recommanded Product: 4-(2,4,4-Trimethylpentan-2-yl)benzene-1,2-diol.
