This study presents the synthesis of petroleum sulfonate (PS) via gas-phase SO3 sulfonation in a rotating packed bed (RPB) and the relationship between the interfacial tension (IFT) at the oil-aqueous interface and the composition of PS. Through the process optimization, the content of active matter in the prepared PS could reach up to 42.5%, which was significantly higher than that in the industrial production (38%). Moreover, the oil-aqueous IFT could reach an ultra-low value of 1.41×10-3 mN/m. The analysis results of PS composition and IFT indicated that the oil-aqueous IFT was mainly affected by the content of alkyl benzene, alkyl indane, alkyl acenaphthylene and alkyl naphthalene sulfonates in PS. In addition, a correlation coefficient, which was consistent with the interfacial tension, was established for evaluation of the similarity between PS samples.

旋转填充床气相磺化合成石油磺酸盐:工艺优化及界面张力-组成关系

本研究介绍了在旋转填充床 (RPB) 中通过气相 SO3 磺化合成石油磺酸盐 (PS) 以及油水界面处的界面张力 (IFT) 与 PS 组成之间的关系。通过工艺优化,制备的PS中活性物质含量可达42.5%,明显高于工业生产中的38%。此外,油水IFT可以达到1.41×10-3 mN/m的超低值。PS组成和IFT分析结果表明,油水IFT主要受PS中烷基苯、烷基茚满、烷基苊和烷基萘磺酸盐含量的影响。此外,与界面张力一致的相关系数,
