Separation behaviour of nitroxylene isomers on polyols and polyethers in gas-liquid chromatography.
Of the six nitroxylene isomers, 2,4- and 2,3-nitroxylene are the most difficult to separate by GLC, but they have been effectively separated on various acidic polyols as stationary phases. Although polyethylene glycol could not generally separate the 2,4- and 2,3-nitroxylene isomers, polyethylene glycol 20M could, and polypropylene glycol could separate all the six isomers effectively.
