摘要:

利用自由基聚合反应合成了低分子量聚苯乙烯, 经过端基氧化和磺酰化反应, 制备出一系列极性砜基修饰的低分子量聚苯乙烯. 通过红外光谱(FTIR)、 核磁共振谱(NMR)、 差示扫描量热分析(DSC)以及热重分析(TGA)等手段对聚合物的结构和性能进行了表征, 并通过混合烃萃取分离实验对其芳香烃选择性进行了测试. 结果表明, 随着磺化比例的增加, 甲苯的选择系数和分布系数均显著提高, 表明极性修饰聚苯乙烯对多种芳香烃/链烷烃混合物均具有明显的芳香烃选择性.

Abstract:

A series of sulfonated low molecular weight polystyrene(LOPSS) was synthesized via radical polymerization, oxidation of end-group and Friedel-Crafts acylation reactions. The structures of obtained polymer were investigated by 1H NMR, FTIR and thermal behavior of polymers was performed by differential scanning calorimetry(DSC) and thermo gravimetric analyzer(TGA). The selectivity for aromatic hydrocarbons was tested through extraction of aromatics from aromatic/aliphatic hydrocarbons. The results indicated that with the increase of sulfonylation degree, selectivity coefficient and distribution coefficient of toluene obviously increased. Polystyrene modified with polar monomer has good selectivity for aromatics from all kinds of aromatic/aliphatic hydrocarbons.

Key words: Polystyrene, Extraction, Polar, Sulfonylation, Aromatic hydrocarbon
