Abstract
Cationic surfactants are very important due to their incorporation in several applications including : emulsification, detergency, solubilization and biocides In this thesis, new types of cationic surfactants were synthesized based on complexation reaction between Fe III and amide products, amidation reaction was carried out between morpholine and fatty acids (lauric acid, myristic acid, palmitic acid and stearic acid) to get Morpholin - 4 - yl - dodecan - 1 ne (II a), Morpholin - 4 -yl -tetradecan - 1 - one (II b), Morpholin -4-yl - hexadecan - 1 - one (II c) And Morpholin - 4 - yl-octadecan - 1- one (II d)The products of amidation were reacted with Fe III to get Tri[morpholin - 4 - yl - dodecan - 1 - one]- di[chlorium ferriate] complex (III a), Tri[morpholin - 4 - yl tetradecan - 1 - one]- di[chlorium ferriate] complex (III b), tri[morpholin - 4 - yl - hexadecan - 1 -one]- di[chlorium ferriate] complex(III c) and Tri[morpholin - 4-yl - dodecan -1-one]- di[chlorium ferriate] complex (III d) The chemical structures of the synthesized metallocationic surfactants were confirmed using several analytical tools including : micro elemental analysis to determine the percentage of each element in the structure - fttr Spectroscopic analysis - 1H-NMR Spectroscopic analysis the synthesized metallocationic surfactants were evaluated as surface active agents through measuring their surface properties including surface tension at different temperatures (25, 35 and 45ºC) the surface parameters including critical micelle concentration (CMC), ffectiveness (πcmc), efficiency (PC20), maximum surface excess (Γmax) and minimum surface area (A min) were studied, the thermodynamic parameters of micellization and adsorption of the synthesized cationic surfactants were calculated according to gibb’s adsorption equations, the ΔGOmic, ΔGOads, ΔSmic, ΔSads, ΔHmic and ΔHads of the prepared ferrosurfactants were calculated at different temperatures as 25, 35 and 45 °C. the synthesized metallocationic surfactants were evaluated as biocides for different microorganisms including : gram -positive bacteria, gram - negative bacteria, yeast and mold, the summary of work was as following : the elemental analysis showed that the synthesized metallocationic surfactants are pure compound the fttr spectra showed disappearance of the starting material function group 1-H NMR showed that the distribution of the protons on the chemical structure is as expected tThe surface tension measurements showed the good surface activity of these complexes, the efficiency (PC20) and effectiveness (πcmc) of the synthesized metallosurfactants showed their good surface activity while the maximum surface excess (Γmax) showed the ability of these compounds to accumulate at the interfac the standard free energies of micellization and adsoption (ΔGOmic, ΔGOads) are always negative indicating that the two processes are spontaneou The synthesized metallocationic surfactants showed good biocidal activity towards gm + ve and gm –ve bacteria also yeast and mold.
