用原位拉曼光谱研究了联氨在近临界和超临界水中的分解反应。配备了钻石窗口的高压高温光学元件使我们能够在高达430摄氏度和350大气压的水中进行拉曼测量。用光学元件作为稳态流动反应器，光学跟踪肼的衰变和氨的产生，得到有效的一级速率常数，在400℃时分解0.32 S[超[负]1]。参考文献20，图3。
The decomposition of hydrazine (N[sub 2]H[sub 4]) in near-critical and supercritical water is studied by in situ Raman spectroscopy. A high-pressure, high-temperature optical cell equipped with diamond windows allows us to perform Raman measurements at up to 430[degree]C and 350 atm of water. Using the optical cell as a steady-state flow reactor, the decay of hydrazine and the production of ammonia are followed optically as a function of reaction time to yield an effective first-order rate constant for decomposition of 0.32 s[sup [minus]1] at 400[degree]C. 20 refs., 3 figs.
