在直链烷基苯（LAB）的磺化过程中，除了直链烷基苯磺酸（HLAS）之外，还形成其他产物如砜和酸酐。它们中的大多数在整个磺化过程的老化和水解步骤期间以不同程度转化[Moreno等人（2003）J Surfactant Deterg 6（2）：137-142]。自1988年以来使用HPLC技术以及更早使用高温气相色谱法（HT-GC）能够分离和定量磺酸-酸酐游离油（FO）的所有组分; LAB和砜。本文的目的是回顾目前的知识，游离油分析和讨论一个新的分析方法的基础上，HT-GC的游离油含量的定量。我们将使用这种新方法与其他分析方法（传统重量法）和近红外（NIR）光谱法获得的结果进行比较。
During the sulfonation process of the linear alkylbenzene (LAB) other products like sulfones and anhydrides are also formed in addition to the linear alkylbenzene sulfonic acid (HLAS). Most of them are transformed in different degrees during the aging and hydrolysis steps of the overall sulfonation process [Moreno et al. (2003) J Surfactant Deterg 6(2):137–142]. The use of HPLC technique since 1988 and earlier the use of high temperature gas chromatography (HT-GC) enable the separation and quantification of all the components of the free oil (FO) of the sulfonic acids—anhydrides; LAB and sulfones. The purpose of this paper is to review the current knowledge about the free oil analysis and to discuss a new analytical procedure based on the HT-GC to quantify the free oil content. We will compare the results obtained using this new method with other analytical procedures (traditional gravimetry) and near infrared (NIR) spectroscopy.
