Notes:
A capillary gas chromatographic method for the quantitative analysis of diethylbenzene fractions is described. Estimation of ortho-, meta- and para-isomers and other C9 and C10 aromatic impurities is covered. The conditions developed involve the use of a capillary column of Carbowax-1540 (300 feet × 0.01 inch) under isothermal operation. The retention index data for a number of aromatics are presented at four temperatures (90, 100, 110 and 120°C). The method offers a good choice for any level of concentration both for isomers and impurities commonly encountered within a reasonable analysis time.
