Název v původním jazyce
Field gas chromatographic identification of Adamsite: Derivatization by aliphatic thiols
Popis výsledku v původním jazyce
The report describes the development of a method for identification of the irritant chemical warfare agent Adamsite. Due to its low volatility, it cannot be analyzed directly by gas chromatography. Published procedures for the conversion of organoarsenic compounds to volatile derivatives have not been tested for Adamsite or cannot be used under field conditions. The research was focused on aliphatic thiols, which react with Adamsite by nucleophilic substitution on the arsenic atom. 5 substances were tested (ethanethiol, 1-propanethiol, 2-propanethiol, 1-butanethiol and 1-hexanethiol). The influence of the reaction medium and the time dependence of the reaction were monitored. The objects of interest were the retention characteristics and mass spectra of the newly formed derivatives, the purity of the chromatograms and the characteristics of the peaks. As the most suitable reagents, 1-hexanethiol and 1-butanethiol were identified.
