Interaction of S,N-Derivatives of Alkylhydrazines with Carbon Sorbents

Abstract

S,N-derivatives of alkylhydrazines, including 1,1-dimethylhydrazine, have been synthesized for the quantitative analysis of trace impurities of hydrazines in environmental objects. The molecular-statistical method has been used to calculate the thermodynamic characteristics of their adsorption on graphitic thermal carbon black. The dependences of the thermodynamic functions of S,N-derivatives of alkylhydrazines on their molecular mass and stereochemical features of hydrocarbon radicals have been found. The results have been compared with experimental data obtained by liquid chromatography when studying the interaction of S,N-derivatives of 1,1-dimethylhydrazine with Hypercarb graphitic carbon sorbent.
