摘要
对石油馏分油的氧化产物进行了不同形式的皂化，并将所得到的石油羧酸盐活性剂提浓，实验结果表明：用溶剂皂化制备石油羧酸盐活性剂可提高皂化反应的产率，且所得活性剂的界面活性也较好；分步皂化不仅可提高石油羧酸盐产率，还可得到不同亲油、亲水性的活性剂体系，并根据实际需要可将这些活性剂进行复配。甲醇抽提提纯后的氧化烃，经水相皂化后所得活性剂的界面活性较好；用正己烷一异丙醇一水抽提，石油羧酸盐的纯度和产率都很高，但它在低矿化度下活性差，这可能是正己烷将其亲油组分部分抽提掉的缘故。
In preparation of petroleum carboxylates by saponifying oxidizedhydrocarbon, using organic solvents can increase productivity, and the products obtainedexhibit good interfacial activity. By using multistep saponification, the productivities ofpetroleum carboxylate will be raised also. Otherwise, various surfactant systems withdifferent hydrophile - lipophile properties and meeting the needs for different oilfields canbe gotten by mixing them. Oxidized hydrocarbon purified by methanol extraction canproduce surfactants with very good interfacial activities after saponifying. Purifyingpetroleum carboxylates by hexaneisopropanol - water extraction, the products are higtproductivity and higt purity, althougt their interfacial activities at lower salinity are notgood.
