DETERMINATION OF ACROLEIN IN AIR AS AN OXAZOLIDINE DERIVATIVE BY GAS CHROMATOGRAPHY.

Article abstract of DOI:10.1021/ac00276a032

Acrolein in air (0. 13 to 1. 5 mg/m**3) reacted with 10% (w/w) 2-(hydroxymethyl)piperidine coated on XAD-2 (16/50 mesh) sorbent to produce a bicyclic oxazolidine, 9-vinyl-1-aza-8-oxabicyclo left bracket 4. 3. 0 right bracket nonane. This compound was desorbed from the sorbent with toluene and determined by gas chromatography with nitrogen-specific detection. Separation of this oxazolidine from the oxazolidines of formaldehyde and acetaldehyde was accomplished by use of a 2 m multiplied by 4 mm i. d. column packed with 5% SP-2401-DB on Supelcoport. Sorbent tube samples were collected at a rate of 100 cm**3/min for up to 8 h and found to be stable for at least 4 weeks at room temperature.
