Abstract

The purpose of this study is the development of the simple and precise determination method of ethyl isocyanate (EIC) and propyl isocyanate (PIC) through derivatization using secondary aliphatic amines by gas chromatography with flame ionization detector. The urea derivatives are quantitatively and simultaneously derived from EIC and PIC with secondary aliphatic amines such as dipropylamine, dibutylamine. and dipentylamine in methylene chloride, and confirmed by thin layer chromatography and gas chromatography with mass selective detector. For GC/FID, according to the increasing carbon atom of the amines, the retention time and peak area of the urea derivatives are increased. The instrumental detection limits for EIC and PIC were about 23.3∼34.8 $\mu\textrm{g}$ and 21.6∼28.9 $\mu\textrm{g}$, respectively.
