摘要： In preparing alkanesulphonic acids by sulphoxidation of n-paraffins containing between 12 and 18 carbon atoms, using UV radiation to initiate the reaction (light-water process), a mixture is obtained which spontaneously allows a substantial part of the unconverted n-paraffins to separate from a mixture containing the alkanesulphonic acids together with water, sulphuric acid and n-paraffins.
The aforesaid mixture is fed with one or more alcohols having four or less than four carbon atoms, preferably isopropanol, to form a two-phase mixture.
The two-phase mixture is extracted with supercritical CO 2 , which extracts the n-paraffins, these being recycled to the sulphoxidation process.
The paraffin-free product is suitable for preparing alkanesulphonates of the desired type by neutralisation with suitable bases.
摘要翻译：在通过使用含有12-18个碳原子的正链烷烃进行磺酰化制备烷基磺酸时，使用紫外线辐射引发反应（轻水过程），得到一种混合物，其自发地允许大部分未转化的正链烷烃分离从含有链烷磺酸的混合物与水，硫酸和正链烷烃一起混合。向上述混合物中加入一种或多种具有四个或少于四个碳原子的醇，优选异丙醇，以形成两相混合物。用超临界二氧化碳提取两相混合物，萃取出正链烷烃，将其再循环至硫化过程。无石蜡产品适用于通过用合适的碱中和制备所需类型的链烷磺酸盐。

摘要： Mixtures of C₁₂-C₁₈ n-paraffins with paraffinsulphonic acids having the same number of carbon atoms, water and sulphuric acid, and obtained by sulphoxidation of said paraffins with SO₂ and O₂ in the presence of water and UV radiation are stripped of their excess SO₂ and decanted to separate most of the paraffins, and obtain a residual mixture. The residual mixture is dehydrated according to the invention until a two-phase system forms or at least until the mixture becomes turbid, and the dehydrated mixture either as such or after separating the heavier phase consisting of water and sulphuric acid is extracted with supercritical CO₂, which removes with it the n-paraffins, these being reused in the sulphoxidation process.
