Abstract

The decomposition of hydrazine (N2H4) 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-degrees-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-1 at 400-degrees-C.
