Silicon-modified carbohydrate surfactants VI: Synthesis of carbosilane, silane, polysilane and non-permethylated siloxane derivatives; the wetting behaviour of epoxy-modified precursor liquids on non-polar surfaces

Synthesis and characterization of glucosamide‐based trisiloxane gemini surfactants

“…function was formed, whereas the secondary amino group did not yield a considerable amount of by-products. The amidation of amine functional siloxanes has been reported previously by Wagner and colleagues (36)(37)(38)(39)(40)(41)(42). Equation 2 describes an easy one-step synthesis of the oligoethylene glycol diglycidyl ethers from oligoethylene glycols and epichlorohydrin under phase-transfer conditions (PTC) in the presence of sodium hydroxide.…”

Impact of Molecular Architecture on Surface Properties and Aqueous Stabilities of Silicone-Based Carboxylate Surfactants

“…The addition of the methylene group between silicon atoms can increase the volume fraction of the hydrophobic part, thus increasing the Lifshitz–van der Waals contribution to the surface tension. It is noted that, however, Si–C–Si cannot adopt the conformation at the air/water interface with closely packed methyl groups. , Compare to the Si–O–Si bond that performs a certain electrovalent bond property, the Si–C–Si bond displays a covalent bond that could assure the stabilities of carbosilane surfactants in ionic environments. Nevertheless, few systematic studies focus on the synthesis and aggregation behavior of carbosilane surfactants .…”
