초록

수포작용제의 일종인 sulfur mustard(HD, bis 2-chloroethylsulfide)를 무해한 물질로 전환하기 위한 공정 운영조건을 찾기 위하여 물에 의한 HD 가수분해 반응을 연구하고 분석절차를 수립하였다. 반응은 2단계로 진행하였다. 먼저, HD 10~20 wt%를 $90^{\circ}C$ 물에서 2시간 동안 가수분해 한 후 상온에서 가성소다 수용액(2.1 당량)을 주입하면서 반응시간에 따른 HD의 농도변화를 측정하였다. 이 실험조건에서 HD의 분해효율은 99.99% 이상 이었으며 가수분해 후의 최종 분해물질은 thiodiglycol 68 wt%, 1,2-bis(2-hydroxyethylthio)ethane 8 wt% 및 bis(2-hydroxyethylthioethyl)ether 24 wt% 이었다.

The hydrolysis reaction of sulfur mustard(HD, bis 2-chloroethylsulfide), one type of the blister agents was studied in water to find the operation conditions which can convert HD into less toxic compounds. The reaction was proceeded into two steps. First, 10~20 wt% of HD was hydrolyzed in water at $90^{\circ}C$ for 2 hr and aqueous sodium hydroxide solution(2.1 eq) was subsequently added to the reaction mixture at room temperature. The efficiency of HD hydrolysis at this experimental conditions was greater than 99.99% and the final degradation products of HD were 68 wt% of thiodiglycol, 8 wt% of 1,2-bis(2-hydroxyethylthio)ethane and 24 wt% of bis(2-hydroxyethylthioethyl)ether.
