Quaternary ammonium compounds containing the hydroxyalkyl moiety in the head group have been synthesized. These compounds exhibit a micelle-forming ability, high anticorrosive activity, and antimicrobial action. The compounds of the formula R(CH3)(2)N+(CH2CH2CH2OH)Br- with R = C14H29-C18H37 are characterized by a protective effect higher than 90-99% at 10 mg/l with respect to hydrogen sulfide corrosion, inhibiting properties against carbon dioxide corrosion (84-98% at 10-25 mg/l), and bactericidal action on sulfate-reducing bacteria (10-50 mg/l).

series of quaternary ammonium from amino alcohols and n‐bromoalkanes. The compounds are referred to as CnEtOH, CnPrOH, and CniPrOH (where n = 12 and 14 carbons, EtOH = ethanol, PrOH = propanol, iPrOH = iso‐propanol). Their structures were checked using the usual spectroscopic methods [1H, 13C nuclear magnetic resonance (NMR) and infrared (IR)]. Their physicochemical properties in aqueous solution were
在这项工作中,我们从氨基醇和正溴代烷烃中合成了一系列季铵盐。这些化合物称为C n EtOH,C n PrOH和C n iPrOH(其中n = 12和14个碳,EtOH =乙醇,PrOH =丙醇,iPrOH =异丙醇)。使用常规光谱法[ 1 H,13 C核磁共振(NMR)和红外(IR)]检查其结构。使用电导率,表面张力和紫外线(UV)-可见吸收光谱法研究了它们在水溶液中的理化性质。进行该研究以显示线性疏水链的影响以及OH极性基团相对于N的位置+季铵盐对表面活性剂的理化性质。所研究的表面活性剂的理化性质之间的比较表明,OH基团的位置对临界胶束浓度(CMC),电离度(α),在界面处占据的面积(A min),自由吸附能()和胶束化的自由能()。所述合成表面活性剂和甲基橙之间的分子间相互作用(OM)染料是有关胶束的水合程度,由OM波长(的蓝移位移证明λ最大)和电离(α)的胶束。胶束的CMC,电离度和水合度遵循相同的趋势。
