METAL HYDRAZIDES

Hydrazinium salts, N2H5 X, are acids in anhydrous hydrazine, metallic hydrazides, N2H, are bases. Neutralization in this solvent system involves the hydrazinium and hydrazide ions and is the reverse of equation 7. Metal hydrazides, formally analogous to the metal amides, are prepared from anhydrous hydrazine and the metals as well as from metal amides, alkyls, or hydrides. (The term hydrazide is also used for organic compounds where the carboxyUc acid OH is substituted with a N2H2.) Sodium hydrazide [13598-47-5] is made from sodium or, more safely, from sodium amide (14) ... [Pg.275]

The magnitude of K value for this self-ionization is in the order of which is greater than that for anhydrous ammonia ionizing to ammonium (NR4+) and amide (NH2 ) ions (K 10-33). Anhydrous hydrazine thus forms salts with hahde and other anions of the composition N2H5 X which are acids. Similarly, metallic hydrazides, M N2H3, are bases in anhydrous hydrazine. Most hydrazine salts are unstable and are sensitive to heat and... [Pg.344]
