The Thermal and Catalytic Decomposition of Methylhydrazines
Abstract
The thermal decomposition of methylhydrazine (MMH), 1,1- dimethylhydrazine (UDMH) and trimethylhydrazine (TMH) using a time of flight mass spectrometer is discussed and the catalytic decomposition of MMH and UDMH over heated Shell 405, a spontaneous hydrazine decomposition catalyst, is also reported. Both the catalyzed and uncatalyzed experiments were conducted using a heated quartz chamber directly preceding the leak to the mass spectrometer. The temperature range was from ambient to an upper limit of 1000C. The main products of the thermal degradation of the methyl derivatives of hydrazine are hydrogen cyanide (HCN), nitrogen (N2), and ammonia (NH3); in the catalytic decomposition the main products are N2 and H2, as the NH3 originally formed is decomposed by Shell 405 to yield N2 and H2.
