摘　　要：本文对石油羧酸盐表面活性剂溶液体系进行了系统分析．发现溶液中不仅仅含有羧酸盐，还含有饱和烃、芳烃，酮、醇和极性物等化合物，用气相色谱法测定了各族组分的碳数范围，估算了羧酸的平均分子量Ｍｗ＝２５１．由波谱分析证明，羧酸中除脂肪酸外，还含有带芳环、羟基。Three kinds of petroleum carboxylate surfactant solutions have been systemic analysis. It isfound that the solubilizing action of these surfactant solutions is very strong.The family componentsalkanes, arenes, ketones, alcohols, carboxylic acid and polar compounds have been seperated outfrom the organic compounds extracted from these solations. The carbon nember range of thesecompounds have been determined by gas chromatography. Average molecule weight of carboxylicacid estimated by GC data is Mw=250. Except fatty acids some organic acids with aromatic ring,hydroxyl, elefinic linkage foundamental groups are also present in the carboxylate family, whichhas been provided by wave spectrum analysis.
