    Hydrazine - Wikipedia

    Etymology and history

    The name "hydrazine" was coined by Emil Fischer in 1875; he was trying to produce organic compounds that … See more

    Applications

    The largest use of hydrazine is as a precursor to blowing agents. Specific compounds include azodicarbonamide and azobisisobutyronitrile, which produce 100–200 mL of gas per gram of precursor. In a relate… See more

    Occupational hazards

    Potential routes of hydrazine exposure include dermal, ocular, inhalation and ingestion.
    Hydrazine exposure can cause skin irritation/contact dermatitis and burning, irritation to … See more

    Molecular structure

    Hydrazine, H2N−NH2, contains two amine groups NH2 connected by a single bond between the two nitrogen atoms. Each N−NH2 subunit is pyramidal. The structure of the free molecules was determined by gas electro… See more

    Synthesis and production

    Diverse synthetic pathways for hydrazine production have been developed. The key step is the creation of the N–N single bond. The many routes can be divided into those that use chlorine oxidants (and generate salt) and th… See more

    Reactions

    Hydrazine forms a monohydrate N2H4·H2O that is denser (1.032 g/cm ) than the anhydrous form N2H4 (1.021 g/cm ). Hydrazine has basic (alkali) chemical properties comparable to those of ammonia:
    N2H4 + H2… See more

    In popular culture

    In the fictional book The Martian (also adapted to a feature film) the titular character uses an iridium catalyst to separate hydrogen gas from surplus hydrazine fuel, which he then burns to generate w… See more
