Abstract Three novel fluorinated cationic surfactants were prepared by adopting perfluoro-2-methyl-2-pentene as raw substrate. The as-obtained fluorinated cationic surfactants exhibited excellent surface properties, all of them can reduce the surface tension of water to below 20.00 mN/m at the critical micelle concentrations (CMC). The incorporation of SDS, AOS, APG or LAB into 2-(4-(3,3,4,4,5,5,5-heptafluoro-2
摘要以全氟-2-甲基-2-戊烯为原料,制备了三种新型的氟化阳离子表面活性剂。所获得的氟化阳离子表面活性剂表现出优异的表面性能,在临界胶束浓度(CMC)下,它们都能将水的表面张力降低至20.00 mN / m以下。将SDS,AOS,APG或LAB掺入2-(4-(3,3,4,4,5,5,5,5-七氟-2,2-双(三氟甲基)戊基)苯甲酰胺基)-N,N-与单独的4a相比,二甲基乙烷氧化胺4a在CMC处产生的CMC和表面张力值低得多。特别地,该组合的APG / 4a的表面张力值可以降低到17.31mN / m。出色的表面活性及其与各种烃类表面活性剂的显着相容性,使其成为PFOA(全氟辛酸,
