摘要
Abstract
Fluorocarbon surfactant diperfluorous 2-(2-propoxy-propoxy)propionic ester of polyglycol (I) was synthesized by esterification of perfluoro(2,5-dimethy1-3,6-dioxananoyl) fluoride and polytglycol-400. The prepared surfactant I was characterized by FT-IR, 1H-NMR and 19F-NMR, respectively, and its surface activities were investigated too. The surface tension (γcmc) of surfactant I at critical micelle concentration (CMC) is 17.69 mN.m-1 and the value of CMC is 0.54 g.L-1. The values of CMC and γcmc decrease clearly with increasing temperature, but are little affected by pH value. The prepared surfactant I has good surface activities in both acid and basic solutions; Ca2+ and Mg2+ have little effects on the critical micelle concentration of aqueous solution of surfactant I, and the surface activity of surfactant I is slightly affected by inorganic cation Na+, in other words, the effect of salinity on non-ionic surface-active agent of surfactant I is little. In short, the fluorocarbon surfactant diperfluorous 2-(2-propoxy-propoxy)propionic ester of polyglycol is an excellent surfactant with high surface activity and good resistance to water hardness, water salinity acid and alkali.关键词
