Anilinopropyltrialkoxysilane and preparation method thereof

The invention discloses an anilinopropyltrialkoxysilane and a preparation method thereof. The method comprises the following steps: respectively preparing a chloroplatinic acid/isopropanol solution and an amine/isopropanol solution, mixing the chloroplatinic acid/isopropanol solution with the amine/isopropanol solution, continuously adding diethanolamine, fully mixing above solutions and the diethanolamine, and adding a polymerization inhibitor to obtain a composite catalyst; adding trimethoxyhydrosilane and allylaniline into a reactor, adding the composite catalyst, carrying out stirring heating to make the temperature reach 80-150 DEG C, carrying out heat insulation for 3 h, and cooling the obtained reaction product to room temperature; and filtering the reaction product, collecting the obtained filtrate, and distilling the filtrate to remove the above organic solvent in order to obtain the target product. The preparation method improves the storage stability of the anilinopropyltrialkoxysilane, facilitates
