Hydrazinium chloride is a chemical compound from the group of hydrazinium salts .

Extraction and presentation

Hydrazinium chloride is formed by neutralizing one mole of hydrazine with one mole of hydrochloric acid .

${\displaystyle \mathrm {N_{2}H_{4}+HCl\longrightarrow N_{2}H_{5}Cl} }$

properties

Hydrazinium chloride is a crystalline colorless solid that is easily soluble in water. It decomposes when heated above 240 ° C, producing hydrogen chloride and nitrogen oxides . The compound has an orthorhombic crystal structure (a = 1.249 nm, b = 2.185 nm, c = 0.441 nm) with the space group Fdd 2 (space group no. 43) .

use

Hydrazinium chloride is used as a catalyst in the synthesis of titanium oxide polymers via catalytic sol-gel processes , in the production of amorphous titanium dioxide thin films with high refractive indices and high transparency, and in the production of other chemical compounds. It can also be used to precipitate elements such as gold, palladium, platinum, selenium and tellurium from hydrochloric ore solutions.
