摘要
对ＡＭ－ＡＯＰ_ｎ和ＣＭＣ－ＡＲ１２ＥＯ_ｎ两类高分子表面活性剂与原油形成超低界面张力的研究结果表明，加碱复配后，ＡＭ－ ＡＯＰ_ｎ和 ＣＭＣ－ ＡＲ_１２ＥＯ_ｎ与大庆原油的界面张力分别可达 ２．６ ×１０^（－３）ｍＮ／ｍ和 ３．２ｘ １０^（－３）ｍＮ／ｍ。显微观察表明，碱使胶束解缔是界面张力降低的主要因素。
The ultra-low interfacial tensions (IFT) between aqueous solutions of AM - AOP_n. and CMC - AR_12 EO_n. polymeric surfactants and Daqing crude oil were studied.The results show that the IFT decreased to 2. 6 x 10^(-3) and 3 .2 x 10^(-3)mN/m for AM -- AOP_n. and CMC -- AR_12 EO_n. respectively with the addition of alkali. The microscopic observation showed that the disaggregation of micelles by alkali is the main reason for IFT decrease.
