Abstract

The invention provides tetrasiloxane containing sugar acylamino and a preparation method, and belongs to the technical field of organic compound composition. The tetrasiloxane containing sugar acylamino is a compound obtained in a bonding reaction through silicone, oxygen, nitrogen or carbon in molecules; the preparation method comprises the following steps: propyl chloride tetrasiloxane is prepared by hexamethyldisiloxane and chloride propyl silane at presence of an acid catalyst; N-Beta-ammonia alkyl-Gamma-aminopropyl tetrasiloxane is prepared by propyl chloride tetrasiloxane and alkyl diamine; the tetrasiloxane containing sugar acylamino is prepared by the N-Beta-ammonia alkyl-Gamma-aminopropyl tetrasiloxane and saccharic acid or saccharic acid internal ester in a lower alcohol solvent; the tetrasiloxane containing sugar acylamino cannot be hydrolyzed in the water within 30 days and can be widely applied in the fields of pesticides and the like.

Description

technical field [0001] The invention relates to the field of preparation methods of organosilicon compounds, in particular to a sugar amide group-containing tetrasiloxane and a preparation method thereof. Background technique [0002] In addition to the properties of ordinary surfactants, trisiloxane surfactants also have more advantages than ordinary surfactants. They can be applied to non-aqueous systems, have lower surface tension, and extremely low physiological toxicity. In particular, it has good wetting and spreading properties. [0003] Han Fu (Chinese patent 200410092453.8) reported a method for preparing a glucose amido-modified trisiloxane surfactant, by reacting aminosilane with hexamethyldisiloxane to generate aminotrisiloxane, and then reacting with glucose Acid lactones react to form glucosamidotrisiloxane surfactants. [0004] In this sugar amide-containing trisiloxane surfactant, the carbon chain linking group between trisiloxane and glucose amide is very ...
