  Properties of Dilute Aqueous Solutions of Double-Chain Surfactants, Alkyldodecyldimethylammonium Bromides with a Change in the Length of the Alkyl Chains

  摘要：

  合成了一系列阳离子表面活性剂，即以十二烷基为第一烷基链，以甲基、乙基、丙基、丁基、己基、辛基和癸基为第二烷基链的二烷基二甲基溴化铵，以及以二辛基、二癸基和二十二烷基为对称烷基链的阳离子表面活性剂、并通过测量其水溶液的电导率和气液表面张力来研究它们的性质，从而根据弗鲁姆金方程形式的二维晶格模型确定它们在配方中的临界胶束浓度（cmc）和表面吸附参数。cmc 的变化表明，对于第二烷基链较短的不对称双链表面活性剂来说，每个亚甲基单位从水转移到胶束的自由能很小，随着第二烷基的拉长，其自由能接近于单链和对称双链表面活性剂的自由能。对于所研究的所有种类，转移到空气-溶液界面的自由能随着碳氢链总长度的增加而近似线性下降。对称双链表面活性剂分子的晶格面积随着碳氢化合物长度的增加而减小。在一系列不对称分子中，第二个烷基为己基的分子的晶格面积最大。

  Quaternary ammonium salts (QASs) have been widely used for disinfection purposes because of their low price, high efficacy and low human toxicity for decades. However, precise mechanisms of action nor the powerful versatile agent against all antimicrobial species are known. In this study we have prepared 43 novel N-alkyl monoquaternary ammonium salts including 7 N,N-dialkyl monoquaternary ammonium salts

  几十年来，季铵盐（QASs）价格低廉，功效高，对人体无害，已被广泛用于消毒目的。但是，已知精确的作用机理或针对所有抗菌剂的强大多功能剂。在这项研究中，我们制备了43种新颖的N-烷基单季铵盐，其中包括7个N，N-二烷基单季铵盐，这些盐的碳原子数分别为12、14或16个。我们已经与15种已经发表的QAS一起研究了所有水溶性化合物以及标准苯扎铵盐对G +和G细菌，厌氧孢子形成Cl的抗菌功效。艰难的，酵母，丝状真菌和包膜VZV。为了解决作用机理，亲脂性似乎是决定抗菌功效的关键参数，但是，可能会出现例外情况，因此我们对Q +和G细菌的功效进行了QSAR分析。我们表明，当分子较大，亲脂性更高，极性更小且包含更少的氧原子，与杂原子结合的甲基或与极化的碳原子结合的氢原子时，抗菌活性就更高。另外，从应用的角度来看，我们根据获得的各个化合物的效率配制了混合物，以接收广谱剂。所有配制的混合物完全消除了经测试的G
