Tris(2-chloroethyl)amine is a chemical warfare agent which is considered to be a persistent contaminant highly resistant to decontamination. The time dependence of tris(2-chloroethyl)amine degradation on the water pH value is observed to determine decontamination options using the decontamination of hydroxide-based mixtures which are used by a number of armed forces. The kinetics was observed using thin-layer chromatography and gas chromatography. The time development of tris(2-chloroethyl)amine concentration decrease in the environment with the pH ranging from 7.5 to 12.5 was recorded. The reaction rate constants were established at all observed pH values, half-lifes of reactions and the influence of temperature on the reaction rate at a slightly alkaline pH of 8.5. The equation to estimate the rate constant of the first step of tris(2-chloroethyl)amine hydrolysis at various temperatures was formed. The rate of triethanolamine formation in the samples of neutral to alkaline pH was recorded. The results indicate the substantial influence of pH on tris(2-chloroethyl)amine hydrolysis. The rate constant was significantly increased from a neutral environment to the pH of 12.5 reaching 500% of the original value using alkalisation. The hydrolysis in a neutral environment was also influenced by the analyte concentration. The concentrated solutions hydrolysed more slowly as a result of hydrochloric acid release as the acid lowered the pH value of the environment. The results demonstrate that there is an important kinetic difference between sulphur and nitrogen mustard hydrolysis in an alkaline environment.

三（2-氯乙基）胺是一种化学战剂，被认为是高度耐污染的持久性污染物。观察到三（2-氯乙基）胺降解对水pH值的时间依赖性，以确定使用多种武装力量使用的氢氧化物基混合物的去污方法来确定去污选择。使用薄层色谱法和气相色谱法观察动力学。记录了在环境中pH值从7.5到12.5时三（2-氯乙基）胺浓度下降的时间过程。在所有观察到的pH值，反应的半衰期以及温度在8.5的弱碱性pH下对反应速率的影响下，确定了反应速率常数。形成了在不同温度下估算三（2-氯乙基）胺水解第一步的速率常数的方程式。记录中性至碱性pH值样品中三乙醇胺的形成速率。结果表明pH值对三（2-氯乙基）胺水解的影响很大。从中性环境到使用碱化的pH值达到原始值的500％时，速率常数显着增加。在中性环境中的水解也受分析物浓度的影响。由于盐酸降低了环境的pH值，因此盐酸释放会导致浓缩溶液的水解更缓慢。结果表明，在碱性环境中，硫和氮芥子水解之间存在重要的动力学差异。
