Basic Info of Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride

What is Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride?

Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride is an organosilicon quaternary ammonium salt. Quaternary ammonium salts can adsorb adversely billed microorganisms as well as have a good bactericidal result. Nevertheless, typical quaternary ammonium salts have low chemical task, essentially exist in a complimentary state when used, and also are fairly harmful and bothersome.

The study located that the performance of the organosilicon quaternary ammonium salt prepared by presenting siloxane right into the quaternary ammonium salt structure has undertaken fantastic adjustments. It not just has excellent antibacterial and also bacteriostatic residential or commercial properties, however likewise has no annoying and also carcinogenic impacts on human skin.

Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride Uses

  1. Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride is an organosilicon quaternary ammonium salt. Quaternary ammonium salts can adsorb negatively billed germs and have a good antiseptic result. Dimethyloctadecyl [3-(trimethoxysilyl)propyl] ammonium chloride can be used in the processing of cotton, nylon, polyester and other fiber products, and also has a vast array of uses. Recently, it has actually also been used in non-woven materials, lathered polyurethane, synthetic leather and also other materials.
  2. Dimethyloctadecyl[3-(trimethoxysilyl) propyl]ammonium chloride (dtsacl) is a natural silane that can be utilized as a silica precursor. It forms an oil soluble remedy as well as can be made use of as a solution stabilizer.
  3. Dtsacl can be made use of to change silica. It is utilized to functionalize Fe3O4/ silica core-shell nanoparticles. Dtsacl can be used as a forerunner for the development of silica, 3 as well as memfi zeolites. It serves as a mesopore generator.

Preparation of Dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride

  1. Take by weighing γ-chloropropyl trimethoxysilane (2.782 kilograms, 14 moles) and join in the 150 liters of reactors with condensation and reflux device, after the closed reactor, open the reactor heating mechanism, at 40-80 rpm When the reaction kettle was heated to 40-50 ° C under the stirring speed of /min, began to drip octadecyldimethyl tertiary amine (2.976 kilograms, 10 moles) in the reaction kettle, and the dropping time was 3 hours; At 140°C, keep the constant temperature, react in a closed and mixed solvent reflux state for 36 hours to obtain an organosilicon quaternary ammonium salt product solution, and stop the reaction heating when the conversion rate of the organosilicon quaternary ammonium salt is determined to be 93% by nuclear magnetic resonance method.

  2. After the solution in the reactor is lowered to normal temperature, adjust the pH of the organosilicon quaternary ammonium salt in the reactor to 5.5-6.5 with hydrochloric acid, stir homogeneously for 5-10min, then filter and decolorize with 600-800 mesh diatomaceous earth, remove Impurities, in dimethyl octadecyl [3-(trimethoxysilyl) propyl] ammonium chloride.
