摘要
对肼、甲基肼 (MMH)及 β 羟基乙基肼 (HEH)进行γ射线辐照实验 ,分别用红外光谱和比色分析法对它们的辐解产物叠氮酸 (HN3)进行定性和定量分析。 0 2mol·L- 1MMH与 0 2mol·L- 1HEH的水溶液体系辐照 10～ 50 0kGy后 ,HN3的生成量为 0 1～ 0 4mmol·L- 1,含 3mol·L- 1HNO3的各体系中HN3的生成量为 0 1～ 3 3mmol·L- 1;作为对比的 0 2mol·L- 1肼 - 3mol·L- 1HNO3体系 ,辐照后HN3生成量为 0 2～ 57mmol·L- 1。MMH与HEH辐照后生成的HN3可能是由MMH和HEH辐照体系中的杂质肼所产生的 ,其生成量远低于HN3的爆炸限。
The yields of hydrazoic acid caused by the radiolysis of mono methylhydrazine (MMH) and β hydroxyethyl hydrazine (HEH) are determined by Fourier transform infrared spectroscopy and spectrophtometry. As a comparison, the yield from the hydrazine is also determined. The yield values at 10～500 kGy of the absorbed dose are 0.1～0.4 and 0.1～3.3 mmol·L -1 for the 0.2 mol·L -1 MMH and 0.2 mol·L -1 HEH solutions without and with 3 mol·L -1 HNO 3, respectively, and 0.2～57 mmol·L -1 for 0.2 mol·L -1 hydrazine solution with 3 mol·L -1 HNO 3. At the given experimental conditions, the yields from the MMH and HEH solutions are much lower than those of hydrazine solution and the explosion limit of hydrazoic acid. It is concluded that the small amount of produced hydrazoic acid for the MMH and HEH is probably related to the existence of the hydrazine as the impurity in MMH and HEH solution.
