摘要
不同制备方法得到的石油羧酸盐，其亲油、亲水性有较大差异，利用这些差异进行复配可取得良好的协同效应；在石油羧酸盐体系中，用两种电解质复配调节盐度往往比用一种电解质的效果好；将烃氧化产物和石油羧酸盐活性剂复配也可产生良好的协同效应，成为活性剂本身的良好助剂。
Petroleum carboxylates, made from different crude oil, oil fractions andprocedures of preparation, have different hydrophile-lipophile properties. Mixing thepetroleum carboxylates, good synergism may be obtained. It may be better for using twokinds of electrolytes than only one to control the salinity of the combination system ofpetroleum carboxylates. Better inter facial activities will be obtained in combination ofpetroleum carboxylates with oxidized hydrocarbon.
