  • Sulfur mustard Wikipedia
    Chinese

    201929&ensp·&enspSulfur mustard is the organic compound with formula (ClCH 2 CH 2) 2 S. In the Depretz method, sulfur mustard is synthesized by treating sulfur dichloride with ethylene: SCl 2 + 2 C 2 H 4 → (ClCH 2 CH 2) 2 S. In the Levinstein process, disulfur dichloride is used instead: 8 S 2 Cl 2 + 16 C 2 H 4 → 8 (ClCH 2 CH 2) 2 S + S 8
