最近国外的一些科学家发现氨在稀有气休氪、氙的存在下,用紫外线照射后,生成肼的产率很高。氨在静止状态经光解或射解(radiolysis)作用生成的肼,为量甚少,而当流动线速度自静止状态的零点骤然上升至1780厘米/秒时,肼的产率猛升至84%。氨基经光解或射解作用再化合而生成肼,而肼遇氢原子即分解。因此在给定的加料率下,氢原子的浓度下降,可提高肼的产率。所以应注意阻止氢原子的生成与采用适当的反应物,有选择性地消除氢原子。通过射解作用,使氪与氙完全吸收了射解能量。由于稀有气体离子电荷的互换,促使氨开始转化:
Recently, some foreign scientists found that ammonia in the rare gas off krypton, xenon in the presence of UV irradiation, the yield of hydrazine is high. The amount of hydrazine produced by photolysis or radiolysis of quiescent ammonia was very small, and the yield of hydrazine soared to 84 as the flow linear velocity rose abruptly from a zero at rest to 1780 cm / s %. Amino group by photolysis or radioactive recombination to generate hydrazine, while hydrazine hydrogen atoms that decompose. Therefore, at a given feed rate, the hydrogen atom concentration decreases, which increases the hydrazine yield. Therefore, attention should be paid to prevent the formation of hydrogen atoms and the use of appropriate reactants, the selective elimination of hydrogen atoms. By irradiation, krypton and xenon completely absorb the energy of the radiation. Due to the exchange of noble gas ion charges, prompting ammonia to begin conversion:
