Electron capture detection-gas chromatographic determination of diaminotoluenes in polyurethane foam as heptafluorobutyryl derivatives.
A simple gas chromatographic (GC) method has been developed to determine 2,4- and 2,6-diaminotoluenes in polyurethane foam. Diaminotoluenes were reacted with heptafluorobutyric anhydride in toluene, and the products, bis-heptafluorobutyrates, were determined by GC, using a 3% silicone OV-330 column. The 2,4- and 2,6-diaminotoluenes can be detected as heptafluorobutyryl derivatives by using an electron capture detector at levels of 5 and 2 pg, respectively. Finally, 2.7-3.0 micrograms/g of 2,4- and 1.3-1.9 micrograms/g of 2,6-diaminotoluene were detected in 3 commercial polyurethane foams.
