[Gas chromatographic detection of sebacic acid in the air].

The study described the technique for gas chromatographic identification of sebacic acid in the work zone air in the form of diethyl ether produced due to sebacic acid etherification by absolute ethyl alcohol in the presence of 0.3 ml of concentrated sulphuric acid during heating up to 70 degrees C for 15 min. 1 ml of decane extract of diethyl ether was analyzed by means of gas chromatograph on the column of Im X 0.3 cm, filled with chromosorbe. When sampling 40 l of air the range of measured concentration constituted 2-20 mg/m3. Relative standard variation didn't exceed 0.032.
