英语翻译
There is some disagreement within the surfactant literature as to the exact definition of ‘‘solubilization,’’particularly as the ratio of surfactant to additive decreases,and one approaches the nebulous frontier between swollen micellar
systems and the micro- and macroemulsion regions.For present purposes,solubilization will be defined as the
preparation of a thermodynamically stable,isotropic solution of a substance (the‘‘additive’’) normally insoluble or only
slightly soluble in a given solvent by the addition of one or more amphiphilic compounds at or above their critical
micelle concentration.By the use of such a definition,a broad area can be covered that includes both dilute and
concentrated surfactant solutions,aqueous and nonaqueous solvents,all classes of surfactants and additives,and the
effects of complex interactions such as mixed micelle formation and hydrotropes.It does not,however,limit the
phenomenon to any single mechanism of action.One problem with that definition is that it says nothing about the
relative amounts of surfactant and additive in the system.That question will arise again in the context of microemulsions.For present purposes,we will say that in solubilization,the ratio of additive to surfactant will generally be less than two.The reasons for that limitation will be discussed a bit more later.For a specified solvent system,water or aqueous solutions for example,there are two variables that must be considered in the solubilization process:(1) the molecular nature,purity,and homogeneity of the surfactant and (2) the chemical nature of the additive.From a technological viewpoint,it is important to understand exactly what surfactant structural features serve to maximize the desired solubilizing effect,and the best way to achieve that understanding is through a fundamental knowledge of the molecular
and thermodynamic processes involved.In addition,since most technological applications of solubilization involve
complex multicomponent systems,such factors as temperature,electrolyte content,and the presence of polymeric species
and other solutes must be examined.
with the hydrocarbon tail remaining closely associatied with the micellar core.in some cases,that orientation can potentially have a significant effect on the energetics of the system,as will be discussed in the section on microemulsions

在表面活性剂的文献中,对‘增溶’的确切定义存在一些异议;尤其是随着表面活性剂对添加剂比例的下降,并接近肿胀胶束系统和微乳液与粗乳液区域之间的模糊前沿.作为当前的用途,增溶将被定义为一种物质的各向同性溶液(添加剂)在热力学方面稳定的制剂,在特定溶剂的临界胶束浓度或以上加入一种或多种两亲性化合物,通常会不溶解或只稍微溶解.
By the use of such a definition,a broad area can be covered that includes both dilute and concentrated surfactant solutions,aqueous and nonaqueous solvents,all classes of surfactants and additives,and the effects of complex interactions such as mixed micelle formation and hydrotropes.It does not,however,limit the phenomenon to any single mechanism of action.One problem with that definition is that it says nothing about the relative amounts of surfactant and additive in the system.That question will arise again in the context of microemulsions.
通过使用这个定义,可以涵盖很大范围包括稀释与浓缩的表面活性液体、水性与非水性溶剂、所有级别的表面活性剂与添加剂、以及复杂的相互作用效果例如混合胶束的形成及助水溶物.然而,它没有限制任何单独作用机理的现象.该定义的一个问题是它没有提及系统中表面活性剂与添加剂的相对含量.在微乳液的方面这个问题也会再显现.
For present purposes,we will say that in solubilization,the ratio of additive to surfactant will generally be less than two.The reasons for that limitation will be discussed a bit more later.For a specified solvent system,water or aqueous solutions for example,there are two variables that must be considered in the solubilization process:(1) the molecular nature,purity,and homogeneity of the surfactant and (2) the chemical nature of the additive.
作为目前的用途,我们会指定在增溶里,添加剂对表面活性剂的比例一般会小于二.我们会较后讨论对这个限制的原因.作为一个规定的溶剂体系,例如水或水性溶液,在增溶过程中有两个变数必须要考虑的:(一)表面活性剂的分子本质、纯度及均匀性;(二)添加剂的化学本质.
From a technological viewpoint,it is important to understand exactly what surfactant structural features serve to maximize the desired solubilizing effect,and the best way to achieve that understanding is through a fundamental knowledge of the molecular and thermodynamic processes involved.In addition,since most technological applications of solubilization involve complex multicomponent systems,such factors as temperature,electrolyte content,and the presence of polymeric species and other solutes must be examined.
基于技术观点,很重要的是要精确地了解表面活性剂的什么结构特点能够最大化所期待的增溶效果,实现这目的的最佳方法是通过对涉及的分子与热力作用的基本认识.另外,由于多数的增溶技术运用涉及复杂的多元体系,对这些因素如温度、电解质含量、以及聚合羟基络合物和溶质必须加以检验.
问题补充:with the hydrocarbon tail remaining closely associated with the micellar core,in some cases,that orientation can potentially have a significant effect on the energetics of the system,as will be discussed in the section on microemulsions
由于烃类尾气与胶束内芯保持密切联系,在某种情况下,那种定向可能会对系统的热力有显著的影响,这将会在微乳液的章节讨论.
