A Comprehensive Study on the Synthesis and Micellization of Disymmetric Gemini Imidazolium Surfactants 作者:Zhao, XH (Zhao, Xiaohui)[ 1 ] ; An, D (An, Dong)[ 1 ] ; Ye, ZW (Ye, Zhiwen)[ 1 ] JOURNAL OF SURFACTANTS AND DETERGENTS 卷: 19 期: 4 頁: 681-691 DOI: 10.1007/s11743-016-1830-y 出版年: JUL 2016 查看期刊信息 摘要 Two groups of disymmetric Gemini imidazolium surfactants, [C(14)C(4)Cmim]Br-2 (m = 10, 12, 14) and [C(m)C(4)C(n)im]Br-2 (m + n = 24, m = 12, 14, 16, 18) surfactants, were synthesized and their structures were confirmed by H-1 NMR and ESI-MS spectroscopy. Their adsorption at the air/water interface, thermodynamic parameters and aggregation behavior were explored by means of surface tension, electrical conductivity and steady-state fluorescence. A series of surface activity parameters, including cmc, gamma(cmc), pi(cmc), pC20, cmc/C-20, Gamma(max) and A(min), were obtained from surface tension measurements. The results revealed that the overall hydrophobic chain length (N-c) for [C(14)C(4)C(m)im]Br-2 and the disymmetry (m/n) for [C(m)C(4)C(n)im]Br-2 had a significant effect on the surface activity. The cmc values decreased with an increase of N-c or m/n. The thermodynamic parameters of micellization (Delta G(m)(theta), Delta H-m(theta), Delta S-m(theta)) derived from the electrical conductivity indicated that the micellization process of [C(14)C(4)C(m)im]Br-2 and [C(m)C(4)C(n)im]Br-2 was entropy-driven at different temperatures, but the contribution of Delta H-m(theta) to Delta G(m)(theta) h was enhanced by increasing N-c or m/n. The micropolarity and micellar aggregation number (N-agg) were estimated by steady-state fluorescence measurements. The results showed that the surfactant with higher N-c or m/n can form larger micelles, due to a tighter micellar structure. 關(guān)鍵詞 作者關(guān)鍵詞  isymmetric Gemini imidazolium surfactants; Synthesis; Surface activity; Thermodynamic parameters; Micropolarity; Aggregation numberKeyWords Plus  YRROLIDINIUM HEAD GROUPS; ACTIVE IONIC LIQUIDS; AQUEOUS-SOLUTION; AGGREGATION BEHAVIOR; ZWITTERIONIC GEMINIS; MICELLE FORMATION; ADSORPTION; SOLUBILIZATION; THERMODYNAMICS; NANOPARTICLES作者信息 通訊作者地址: Ye, ZW (通訊作者) 顯示增強組織信息的名稱 Nanjing Univ Sci & Technol, Sch Chem Engn, Nanjing 210094, Jiangsu, Peoples R China. 地址: 顯示增強組織信息的名稱 [ 1 ] Nanjing Univ Sci & Technol, Sch Chem Engn, Nanjing 210094, Jiangsu, Peoples R China 電子郵件地址:yezw@mail.njust.edu.cn 基金資助致謝 基金資助機構(gòu) 授權(quán)號 Six Talent Peaks Program of Jiangsu Province, China JNHB-001 查看基金資助信息 出版商 SPRINGER HEIDELBERG, TIERGARTENSTRASSE 17, D-69121 HEIDELBERG, GERMANY 類別 / 分類 研究方向:Chemistry; Engineering Web of Science 類別:Chemistry, Applied; Chemistry, Physical; Engineering, Chemical 文獻(xiàn)信息 文獻(xiàn)類型:Article 語種:English 入藏號: WOS:000381999800004 ISSN: 1097-3958 eISSN: 1558-9293 其他信息 IDS 號: DU1WB Web of Science 核心合集中的 "引用的參考文獻(xiàn)": 46 Web of Science 核心合集中的 "被引頻次": 0 |
