Studies on Synthesis and Surface Activities of Glutamic Acid Dialkyl Ester

Abstract

Abstract: A series of glutamic acid dialkyl esters (abbreviated as 2R-GE) as new surfactants were synthesized.The surfactants have two long alkyl chains, and both of them are C₈, C₁₀, C₁₂, C₁₄, C₁₆, C₁₈, and C₁₈^△9,10 respectively.The structures of the products were identified by IR and NMR.Through measurement of the interfacial tension and surface pressure, the surface activities were studied.The results show that they are a series of surfactants with much better activity.

Key words: Glutatnic acid dialkyl ester, Surfactant, Surface activity
