Synthesis and Characterization of Glycoside-Based Trisiloxane Surfactant

The synthesis of glycoside-based trisiloxane surfactants of the general formula Me₃SiOSiMeR¹OSiMe₃ (R¹ = (CH₂)₃(OCH₂CH₂)₂OR², R² = glycosyl) is described, and the surface activity properties of the surfactant are studied. Diethylene glycol monoallyl ether glycoside is synthesized by reacting the diethylene glycol monoallyl ether with glucose. The glycoside-based trisiloxane surfactant is prepared by hydrosilylation of the precursor glycoside with hydrogen-containing trisiloxane. The product is structurally characterized by IR, ¹H NMR and MS. The surface tension of an aqueous solution is reduced to approximately 20 mN m⁻¹ at concentration level of 10⁻⁴ mol L⁻¹.
