Synthesis of Anionic Surfoce Active Agents from Fatq Acid Hydroides Containing Heterocyclic iltoiety

Sodium salt of a-sulphonated fatty acid hydrazide was used as starting material to synthesis some important hl!terocycles as oxadiazoles to produce novel groups of anionic surfactants having a double function, antimicrobial and surface active agents. The structure of these compounds was performed by FTIR and CHN-analysis. The physical properties as (Density, pH, Concentration, Color, Viscosity and Stability to hydrolysis) were determined. The surface active agents were used in (O/W) emulsions depend on value of (HLB) [Hydrophilic-Lipophilic Balance].
