Abstract

Hydrazinium salts of 2,4-dichlorophenylacetic acid, phenoxyacetic acid, 2,4-dichlorophenoxyacetic acid, diphenylacetic acid, cinnamic acid, and picolinic and nicotinic acids have been prepared by accomplishing neutralization of aqueous hydrazine hydrate with the respective acids. Formation of these hydrazinium salts has been confirmed by analytical, IR spectral, and thermal studies. IR spectra of the salts register N–N stretching frequencies of ion in the region 963–951 cm−1 and the frequencies of ion in the region 1047–1026 cm−1. Thermal decomposition studies show that the hydrazinium salts undergo melting followed by endothermic decomposition into carbon residue as the endproduct.
