Abstract

A series of N-alkyl-N,N-dimethyl-N-(2,3-epoxy propyl) ammonium chloride (CnEAC, n = 10, 12, 14, 16) with alkyl of decyl, dodecyl, tetradecyl, and hexadecyl were synthesized. The adsorption properties of CnEAC under the different temperatures, concentrations, interfacial oscillation frequencies as well as the inorganic salts (NaCl and Na2CO3) at air/water interface were investigated by interfacial dilatational rheology. The dilatational properties of CnEAC solutions including complex moduli, elastic moduli and viscosity moduli increased with oscillation frequency. The elastic moduli were higher than those of viscosity ones. With different hydrogen carbon length, the complex moduli of CnEAC showed different changing role with their concentration and temperature. Inorganic salts compressed the oppositely charges on CnEAC micelle surface and induced the decrease of both complex and viscosity moduli.

N-十四烷基-N,N-二甲基-N-(2,3-环氧丙基)氯化铵与无机盐在空气/水中的吸附性能

摘要

一系列N-烷基-N , N-二甲基-N- (2,3-环氧丙基)氯化铵(C n EAC, n  = 10, 12, 14, 16) 具有癸基、十二烷基、十四烷基和合成十六烷基。通过界面膨胀流变学研究了C n EAC 在不同温度、浓度、界面振荡频率以及无机盐(NaCl 和Na 2 CO 3)在空气/水界面下的吸附特性。C n的膨胀特性EAC 解决方案包括复模量、弹性模量和粘度模量随着振荡频率的增加而增加。弹性模量高于粘度模量。随着氢碳长度的不同,C n EAC的复模量随着其浓度和温度的变化而表现出不同的变化作用。无机盐会压缩 C n EAC 胶束表面的相反电荷,并引起复合模量和粘度模量的降低。
