The H-point standard addition method (HPSAM), based on a spectrophotometric measurement for the simultaneous determination of hydrazine and acetylhydrazine, is described. This method is based on the difference between the rates of their reactions with N,N-dimethylaminobenzaldehyde (DAB) in the presence of sodium dodecyl sulfate (SDS) in acidic media. The results showed that hydrazine and acetyl...

A fluorescent probe, 7-(diethylamino)-2-oxo-2H-chromene-4-carbaldehyde (probe 1), was designed and synthesized for the sensitive detection of hydrazine. The addition of N2H4 caused the fluorescence intensity of probe 1 to decrease. The probe's fluorescence was turn-off after adding N2H4, which could be observed under UV light at 365 nm. Moreover, once treated with different concentrations N2H4 ...

Crystals of the title compound, C(10)H(8)N(2)O(2), were obtained from a condensation reaction of hydrazine hydrate with furfural. In the crystal structure, the mol-ecule is centrosymmetric and almost planar and the furan rings are parallel by symmetry.

Hydrazine borane (N(2)H(4)BH(3)) is the novel boron- and nitrogen-based material appearing to be a promising candidate in chemical hydrogen storage. It stores 15.4 wt% of hydrogen in hydridic and protic forms, and the challenge is to release H(2) with maximum efficiency, if possible all hydrogen stored in the material. An important step to realize this ambitious goal is to synthesize HB with hi...

The title compound, C(5)H(6)ClN(3), was synthesized by the reaction of 2,3-dichloro-pyridine and hydrazine hydrate. An intra-molecular N-H⋯Cl hydrogen bond results in the formation of a planar (mean deviation 0.038 Å) five-membered ring. In the crystal, inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into a three-dimensional network.

The title compound, C(12)H(12)N(4), was synthesized by the reaction of hydrazine hydrate and 9-methyl-3,4,6,7-tetra-hydro-2H-xanthene-1,8(5H,9H)-dione in ethanol. In the crystal, the mol-ecule lies across an inversion centre. The pyridazine rings are coplanar and the C(6) rings adopt envelope conformations.

In situ morphological transition and turn-on fluorescence of self-assembled NDI derivatives driven by hydrazine hydrate are realized through H-bonding and charging of aromatic building blocks, demonstrating a stimuli-responsive supramolecular system useful for visual detection of hydrazine hydrate.

Hydrazine in water samples is determined by constant current chronopotentiometry in porous carbon electrodes. Hydrazine in alkaline solutions is oxidised to nitrogen in the pores of the electrode by constant current. Two types of electrodes made of reticulated vitreous carbon (RVC) were used, one fabricated from crushed RVC particles, the other with the original RVC material of 100 ppi porosity...

Boron- and nitrogen-based materials have shown to be attractive for solid-state chemical hydrogen storage owing to gravimetric hydrogen densities higher than 10 wt% H. Herein, we report a new derivative of hydrazine borane N₂H₄BH₃, namely lithium hydrazinidoborane ammoniate LiN₂H₃BH₃·0.25NH₃. It is easily obtained in ambient conditions by ball-milling N₂H₄BH₃ and lithium amide LiNH₂ taken in eq...

Hydrazine fuel-cell technology holds great promise for clean energy, not only because of the greater energy density of hydrazine compared to hydrogen but also due to its safer handling owing to its liquid state. However, current technologies involve the use of precious metals (such as platinum) for hydrazine oxidation, which hinders the further application of hydrazine fuel-cell technologies. I...
