3 results about "Ene reaction" patented technology

The invention belongs to the technical field of organic silicon chemistry and surfactants, and provides anionic silicon resin as well as a preparation method and application thereof in order to solve the problem that a traditional organic silicon surfactant is mainly non-ionic and is easy to hydrolyze. (Me3SiO0.5) a (R2Me2SiO0.5) b (Me2SiO) c (R2MeSiO) d (MeSiO1.5) e (R2SiO1.5) f (SiO2) g, in which a is 4 to 20, b is 0 to 15, c is 2 to 30, d is 0 to 15, e is 4 to 25, and f is 6 to 20; g is 20 to 50; r2 is (CH2) n + 1S (CH2) m + 3R1M, and R1 is SO3 <->, PO32 <-> or COO <->; m is Na < + >, K < + > or NH4 < + >; n = 0 or 2; and m = 0-9. The silicon resin is prepared by sulfydryl-alkene reaction, and has the core of silicon resin and excellent surface activity.

The invention belongs to the technical field of organic silicon polymer materials, and provides cationic organic silicon: (Me3SiO0.5) a (R2Me2SiO0.5) b (Me2SiO) c (R2MeSiO) d (MeSiO1.5) e (R2SiO1.5) f (SiO2) g, a being 7-12, b being 0-10, c being 4-30, d being 2-15, e being 4-15 and f being 6-30, aiming at the problems of poor hydrolysis resistance and antibacterial property of the existing organic silicon. G is 30 to 50; r2 is (CH2) n + 1S (CH2) m + 3R1M, and R1 is + N (CH3) 3, + N (C2H5) 3, + N (CH3) 2CH2CH2OH, a pyridine cation or an imidazole cation; m is Cl <->, Br <->, I <-> or BF4 <->; n = 0 or 2; and m = 0-9. And the sterilization effect can be improved by adopting sulfydryl-alkene reaction for preparation.
