聚甘油全氟壬烯基醚的合成与表面性能
Synthesis and Surface Activity of Perfluorononenyl Decaglycerolyl Ether
摘要
Abstract
A nonionic fluorocarbon surfactant-perfluorononenyl decaglycerolyl ether (PDE) was synthesized in the presence of Na2CO3 using perfluorononene (PFN) and decaglycerol (PG-10) as raw materials and N,N-dimethylformamide (DMF) as solvent. The surfactant prepared was characterized by IR and 19F-NMR, and the etherification reaction conditions were optimized. The critical micelle concentration (CMC) and emulsibility of the prepared PDE for benzene-H2O were investigated. The results show that its CMC is 22.5 mN⋅m-1 when decaglycerol was esterified with perfluorononene in solvent DMF and catalyzed by Na2CO3 at 50℃ for 6 h with n(PG-10) : n(PFN) : n(Na2CO3) = 1:1:1. The emulsifying ability of 1 g⋅L-1 PDE aqueous solution for the benzene-H2O system is 746 s with foam volume (V) of 75 mL and the maintaining time for half foam volume is 77 s. The study indicates that PDE is an excellent nonionic fluorocarbon surfactant and emulgent.关键词
