双氧水冷漂助剂液中润湿剂的分离和鉴测

Separation and Identification of Wetting Agent from Auxiliary Agent Solution of H_2O_2 Cold Pad-batch Bleach

双氧水冷漂助剂液中的润滑剂——烷基硫酸钠可以在四级氧化铝柱上用氯仿和乙醇—水的淋洗体系进行分离而获得纯品;用NMR和GC法进行结构分析;两相滴定法测定其含量。

Pure sodium alkylsulfate is separated from auxiliary agent solution of H_2O_2 cold pad-batch bleach with A1_2O_3(Ⅳ)column by using chloroform, ethanol: water(1:1) as eluate. Sodium alkylsulfate's structure is identified by NMR spectrometry and gas chromatography. Total content is measured by two-phase titration method.
