摘要

通过琥珀酸酰胺与不同的溴烯烃反应，制备了三种Gemini两亲化合物。不同的光谱方法强调了它们的化学结构。在20、40和60℃下测量表面张力。尾部最长的Gemini表面活性剂随着混合温度的升高，表面参数值有所提高。两者(ΔGoads) &(ΔGomic)的数据为负，说明吸附和胶束过程是自发发生的，而(ΔSoads)和(ΔSomic)的正表明这两个过程更有秩序。热力学行为随着链长的增加而增加。制备的两亲体对细菌和真菌均具有抗菌活性。

Three novel Gemini amide amphiphilics synthesis, characterization, thermodynamics, surface properties and biological activity

Three Gemini amphiphiles had prepared through reaction of amide of succinic acid with different bromo olefins. Their chemical structure was emphasized different spectroscopic methods. the surface tension measurements were investigated at 20, 40 and 60 °C. The Gemini surfactant with the longest tail clarified enhancement of surface parameters values with elevating mixture temperature.

Both (ΔG^o_ads) & (ΔG^o_mic) data are negative, providing spontaneously occurrence of adsorption and micellization processes while the positivity of (ΔS^o_ads) &(ΔS^o_mic) revealing more order for both processes. Thermodynamic behaviour increases by raising chain length. All of fabricated amphiphiles exhibited antimicrobial activity against bacteria and fungi.

期刊介绍： Egyptian Journal of Petroleum is addressed to the fields of crude oil, natural gas, energy and related subjects. Its objective is to serve as a forum for research and development covering the following areas: • Sedimentation and petroleum exploration. • Production. • Analysis and testing. • Chemistry and technology of petroleum and natural gas. • Refining and processing. • Catalysis. • Applications and petrochemicals. It also publishes original research papers and reviews in areas relating to synthetic fuels and lubricants - pollution - corrosion - alternate sources of energy - gasification, liquefaction and geology of coal - tar sands and oil shale - biomass as a source of renewable energy. To meet with these requirements the Egyptian Journal of Petroleum welcomes manuscripts and review papers reporting on the state-of-the-art in the aforementioned topics. The Egyptian Journal of Petroleum is also willing to publish the proceedings of petroleum and energy related conferences in a single volume form.
