The synthesis of quaternized glucosamide-based trisiloxane surfactant (QGS) of the general formula Me3SiOSiMeR1OSiMe3 (R1 = (CH2)3N+(CH3) 2(CH2)2R2, R2 = glucosamide group) was described, and the surface activity properties of the surfactant were studied. The N-[2-(dimethylamino)ethyl]-d-gluconamide was synthesized by amidation of the ethylenediamine with d-gluconolactone. The 3-(3-chloropropyl)-1,1,1,3,5,5,5-heptamethyltrisiloxane was prepared by the acid-catalyzed reaction of a silane monomer. The QGS was prepared by quaternization of the precursor halogenated hydrocarbon with a tertiary amine. They were structurally characterized by IR,1H NMR and MS. And it reduced the surface tension of water to approximately 21 mN m-1 at concentration levels of 10-3 mol L-1.
Synthesis and Solution Behavior of Sulfonate-Based Silicone Surfactants with Specific, Atomically Defined Hydrophobic Tails
Huang, Yue,Guo, Mengdong,Feng, Shengyu
, p. 9785 - 9793 (2019)
A series of sulfonate-based silicone surfactants with different hydrophobic groups were synthesized. Two synthetic strategies are introduced to permit exquisite control over the hydrophobic moieties. Solution behavior of these surfactants was investigated

Catalytic reactivity of Si-H bond of di-, trisiloxanes with allyl chloride in the presence of platinum catalyst has been examined. Hydrosilylation process competes with hydrogen substitution by chlorine and/or propenyl group. The effect of the reaction conditions as well as structure of siloxane on the yield and selectivity of the number of products has been discussed. Several consecutive-competitive processes have been identified. The results obtained can be helpful in the study of the catalytic hydropolysiloxanes reactions with allyl derivatives-systems of great practical importance, to produce commercial functionalized silicones.
