烷基苯基聚氧乙烯醚系列硫酸盐的合成

SYNTHESIS OF SERIES OF ALKYLPHENYL POLYOXYETHYLENE ETHER SULFATES

以烷基苯基聚氧乙烯醚(OP系列)为原料与氯磺酸反应,然后分别用氢氧化钠和氨水中和,经进一步提纯,制得相应的硫酸盐。并对原料和产物的NMR和FTIR谱图进行了分析比较,确认-SO_3H基团取代了端羟基上的氢,而不是苯环上的氢。

The title compounds were synthesized by the reaction of alkylphenyl polyoxygthylene ether with ohlorosulfonio aoid, and neutralized with 10%(m/m) sodium hydroxide or amonium, then the products were purified by extraction with isopropanol.The NMR and FTIR spectra of the raw material were compared with its sulfates, it is clear that the sulfonic group substitutes the hydrogen of hydroxyl group,instead of the hydrogen of benzene ring.
