【摘要】 考察了5种含聚氧乙烯链的居贝特甜菜碱溶液与克拉玛依原油在40℃下的动态界面张力与质量分数间的关系。结果表明,对于质量分数为0.01%～0.2%的GC16(3),GC16(5)和GC16(7)体系及GC20(5)和GC20(9)体系,当碳链长度相同时,随着聚氧乙烯链的增长,界面张力逐渐升高;当聚氧乙烯数相同时,随着碳链长度的增加,界面张力降低。更多还原

【Abstract】 Relationships of dynamic interfacial tension and mass fraction between five kinds of Guerbet betaine with ethylene oxide groups and Karamay crude oil at 40 ℃ were investigated.Results showed that,for the systems of GC16(3),GC16(5) and GC16(7) as well as the systems of GC20(5) and GC20(9) with mass fraction of 0.01%~0.2%,the interfacial tension gradually increases with the increase of ethylene oxide groups at the same length of carbon chain,while the interfacial tension decreases with the increase of length of carbon chain at the same ethylene oxide groups.更多还原
