dangerous pests. It is a challenge to identify alternatives to the ordinary insecticides with new mode of action to be used for mosquitoes’ control in an environmentally sustainable manner. Using a facile two-step procedure, three novel series of sulfonamide-incorporating quaternary ammonium iodides (3a-i, 4a-i and 5a-i) were synthesized and their chemical structures were successfully characterized.

In this report, three novelsulphonamides based cationic surfactants have been produced, and their structure configurations were clarified by various spectroscopic approaches (13C and 1H NMR). The corrosion protection characteristics of the as-prepared compounds for C1018-steel in carbon dioxide saturated 3.5% NaCl has been inspected and categorized by weight loss, Tafel polarization (PDP), electrochemical
在本报告中,生产了三种新型的基于磺酰胺的阳离子表面活性剂,并通过各种光谱方法(13 C和11 H NMR)。通过重量损失,Tafel极化(PDP),电化学阻抗谱(EIS),X射线光电子能谱(XPS)检查并分类了所制备的C1018钢在二氧化碳饱和的3.5%NaCl中的腐蚀防护特性。 ),场发射扫描电子显微镜(FE-SEM)和能量色散X射线光谱(EDX)方法。此外,电导率和表面活性特征被应用于检查它们的胶束化和吸附。结果表明,这些低剂量的生物活性抑制剂对甜味条件下的C1018钢腐蚀具有有价值的保护能力,在5×10 -4时范围为94.5至99.5%。 M添加剂浓度。PDP图谱表明,所制备的表面活性剂是混合抑制剂,其吸附遵循Langmuir等温线模型。FESEM,EDX和XPS检查表明,在金属/介质界面处形成了保护膜吸附的表面活性剂。DFT计算,蒙特卡洛(MC)模拟,分子静电势(MEP),Fuku

esterified with chloroacetic acid to afford fatty chlorides mixture. Parallelly, tertiary amine-tethering various aryl sulfonamides (3a–e) were prepared from the reaction of sulfonyl chlorides with a primary amine-tertiary amine hybrid compound. Finally, the target cationic surfactants were obtained via quaternization of the tertiary-N in 3a–e with the fatty chlorides. The surface activity and thermodynamic
