Usage

General Description

1,1,4,4-Tetramethyl-2-tetrazene is a chemical compound consisting of four methyl groups attached to a central tetrazene molecule. It is a high-energy, sensitive explosive material with potential applications in propellants and pyrotechnics. Due to its instability, it requires careful handling and storage to prevent accidental detonation. It is also a toxic and potentially hazardous substance that poses health risks if mishandled. Its chemical properties make it a potential candidate for use in military and aerospace applications, but its hazardous nature necessitates strict safety precautions and regulations for its production and use.

Gas-Phase Reaction of 1,1-Dimethylhydrazine with Nitrogen Dioxide

The gas-phase reaction of part-per-million concentrations of nitrogen dioxide with 1,1-dimethylhydrazine in air and in N2 at 298 K was investigated by in situ long-path Fourier transform infrared (FT IP) spectroscopy.In both air and N2, the reaction occurs with an apparent overall rate constant (defined in terms of rates of hydrazine decay) of (2.3 +/- 0.2) * 10-17 cm3 molecule-1 s-1.The major products were nitrous acid and tetramethyltetrazene-2, with the overall reaction stoichiometry being (CH3)2NNH2 + 2NO2 -> 2HONO + 1/2 (CH3)2NN=NN(CH3)2, regardless of initial reactant concentration ratios or whether the reaction was carried out in air or in N2.There was no observable reaction of NO with (CH3)2NNH2 in N2.However, when NO2 was also present, NO participates in the reaction, causing formation of N2O, N-nitrosodimethylamine, and significant amounts of an unidentified compound believed to be an N-nitrosohydrazine, in addition to HONO and tetramethyltetrazene-2.Probable mechanisms accounting for these observations are discussed.

Catalyst for the degradation of 1,1-dimethylhydrazine and its by-product N-nitrosodimethylamine in propellant wastewater

A three-component metal catalyst was prepared and used in the process of catalytic wet peroxide oxidation (CWPO) for the degradation of unsymmetrical dimethylhydrazine (UDMH) in propellant wastewater with H2O2. It was structurally characterized using scanning electron spectroscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and energy-dispersive X-ray spectroscopy (EDX), and its catalytic activity was evaluated using indexes such as the efficiency of UDMH degradation and chemical oxygen demand (COD) removal and the concentrations of ammonia (NH3-N), formaldehyde (HCHO), total nitrogen (TN), total organic carbon (TOC) and N-nitrosodimethylamine (NDMA). Besides, the reaction system was monitored using UV-Vis full wavelength scanning spectroscopy and liquid chromatography-mass spectroscopy (LC-MS). As a result, it was observed that the degradation mechanism involved OH attacking the amino group and homocoupling in UDMH with the simultaneous transformation of the active component CuII/I. Based on investigation of the reaction factors (H2O2 dosage, temperature, catalyst dosage, pH and initial concentration of UDMH) focusing on the removal of NDMA, the optimal conditions for CWPO with a three-component metal catalyst were determined. The high treatable concentration of UDMH (500 mg L-1), rapid rate and good reusability with a high efficiency of UDMH degradation and COD removal (99.9% in 10 min and 94.6% in 30 min, respectively) and the low concentration of NDMA are merits of the present catalyst.

REACTIONS OF 1,1-DIALKYLDIAZENIUM SALTS WITH KETONE ETHYLHYDRAZONES

By reaction of dialkyldiazenium salts with ketone ethylhydrazones, we prepared and characterized 3,3-disubstituted 3,4-dihydroformazans for the first time.The composition of the reaction mixtures indicates a lower (as compared with aldehyde hydrazones) reactivity of ketone hydrazones.
