| 摘 要： | 氨基氰在水热环境，尤其在超临界水中的反应化学实验结果表明，氨基氰可以通过自聚合作用，生成较高分子量的氮杂环混合物，进而水解并最终转化成ＣＯ２和ＮＨ３。实验还证明，超临界水可以有效地破坏那睦含有危险的或剧毒的有机资料，使之转化成无毒无在的Ｈ２Ｏ，ＣＯ２，ＮＨ３和无机盐等，根据实验结果，提出水解反应的可能机制是水的亲核加合。

| Abstract: | Experimental results on reactive chemistry of cyanamide in hydrothermal, especiallyin supereritical water indicate that cyanamide can be converted into aqueous NH_3 andCO_2, either through direct hydrolysis or through polymerization. In the second case,cyanamide firstly polymerizes into a mixture of higher molecular weight cyclic azinesbefore ultimately hydrolysis. Experimental results also demonstrate that supercriticalwater can efficiently destroy organic wastes which contain hazardous or toxic materialsand can transform them into nonpoisonous innocent H_2O, NH_2, CO_2, and inorganicsalts etc. Based on the experimental results, it is proposed that the prossiblemechanism of hydrolysis reaction is nucleophilic addition of water. |
