Abstract

The invention discloses an organosilicon quaternary ammonium salt containing alkyl group and glycosylamide group, and a preparation method thereof. The invention relates to the technical field of organic compound synthesis. The substance is a compound obtained by a bonding reaction with silicon and nitrogen, oxygen or carbon formed in molecules. The preparation method comprises the following steps: dimethyl aminoalkyl glycosylamide is produced by using N,N-dimethyl alkyl diamine and sugar acid or sugar acid lactone in a low-carbon alcohol solvent; the dimethyl aminoalkyl glycosylamide is subjected to a reaction with chloropropyl silane in a polar solvent under the catalysis of an inorganic iodide; after extraction, glycosylamide-modified silane quaternary ammonium salt is obtained; and the glycosylamide-modified silane quaternary ammonium salt is subjected to a reaction with hexamethyldisiloxane, cyclosiloxane and alkylsilane under the effect of an alkaline catalyst, such that the organosilicon quaternary ammonium salt containing alkyl group and glycosylamide group is obtained. The product has a surface tension of 21-23mN / m, and is applied in cosmetic formulas as a cosmetic humectant and emulsifier.

Description

Technical field [0001] The invention relates to a compound obtained by forming a silicon-containing bond in the molecule with or without nitrogen, oxygen or carbon bonding reaction, and particularly relates to an organosilicon quaternary ammonium salt containing an alkyl group and a sugar amide group and a preparation method thereof. Background technique [0002] In addition to the properties of ordinary surfactants, silicone surfactants also have more advantages than ordinary surfactants. They can be used in non-aqueous systems, have lower surface tension, good wetting and spreading, No precipitation at low temperature, very low physiological toxicity, high and low temperature resistance, etc. [0003] Wagner R. (Applied Organometallic Chemistry, 1996, 10, 437) reported a method for preparing sugar amide-modified polysiloxane by linking epoxy-modified polysiloxane with glucose through ethylene diamine to obtain Sugar amide modified polysiloxane. [0004] von Braunmühl V (Polymer, ...
