摘要: Abstract In this work we present a green synthetic pathway for the obtaining of bio-surfactants derived from glycerol. By extending Lewis acid catalyzed reaction between glycidol and primary alcohols obtained good conversion to desired monoalkylglycidyl ether (MAGE) long chain (n-octanol, n-decanol n-dodecanol) reaching initial turnover frequency TOF up 2633 h−1in case octanol. The MAGEs were fully characterized critical micelle concentration (CMC) was determined all using spectrophotometric approach such as pyrene method with peak difference (P2–P7) linear fitting (octylglyceryl ether: 0.97 ± 0.02 mM; decylglyceryl 0.85 ± 0.03 mM; dodecylglyceryl 0.71 ± 0.04 mM).
