Synthesis and interfacial properties of sugar-based surfactants composed of homo- And heterodimers

Dimeric sugar-based amphiphiles were synthesized starting from D-glucose and a commercial mixture of dodecyl and tetradecyl alcohols by a simple procedure. Three different spacers (glutaryl, succinyl, and terephthaloyl) were used to link the sugar moieties through O-2 or O-6. Dimeric compounds are composed by mixtures of homodimers (C-12/C-12) and heterodimers (C-12/C-14). The interfacial properties of these nonionic gemini surfactants are described.Fil: Castro, Mariano Javier Luis. Universidad de Buenos Aires. Facultad de Ciencias Veterinarias.
