Degradation of the king of chemical warfare agent, 2,2' dichloro diethyl sulphide (HD), and its simulant 2 chloroethyl ethyl sulphide (CEES) were investigated on the surface of porous vanadium oxide nanotubes at room temperature (30 ± 2°C). Reaction kinetics was monitored by GC-FID technique and the reaction products were characterized by GC-MS. Data indicates that HD degraded faster relative to CEES inside the solid decontaminant compared to the reported liquid phase degradation of CEES and HD. Data explores the role of hydrolysis, elimination and oxidation reactions in the detoxification of HD and CEES and the first order rate constant and t(1/2) were calculated to be 0.026 h(-1), 26.6h for CEES and 0.052 h(-1), 13.24h for HD. In this report faster degradation of HD compared to CEES was explained on the basis of porous structure.
在室温（30±2°C）下，研究了多孔氧化钒纳米管表面上化学战剂之王 2,2' 二氯二乙硫醚（HD）及其模拟物 2-氯乙基乙基硫醚（CEES）的降解情况。通过 GC-FID 技术监测反应动力学，并用 GC-MS 对反应产物进行了表征。数据表明，与 CEES 在液相中的降解相比，HD 在固体去污剂中的降解速度相对较快。数据探讨了水解、消除和氧化反应在 HD 和 CEES 解毒中的作用，计算出 CEES 和 HD 的一级反应速率常数和 t(1/2)分别为 0.026 h(-1)、26.6 h 和 0.052 h(-1)、13.24 h。在本报告中，根据多孔结构解释了 HD 比 CEES 降解速度更快的原因。
