- Preparation method for anilinopropylalkoxysilane
-
The invention provides a preparation method for anilinopropylalkoxysilane. The preparation method is characterized by comprising the steps of: under a condition of 130-180 DEG C, adding poly aniline, aniline and chloropropylalkoxysilane into a reactor; after a substitution reaction is finished, rectifying a filtered and separated liquid phase to obtain chloropropylalkoxysilane and excessive aniline, wherein the excessive aniline is recycled; and after regenerative treatment on the filtered and separated polyaniline such as neutralization and drying, recycling an obtained deacid agent. The yield of anilinopropylalkoxysilane reaches over 85%, and the selectivity of the anilinopropylalkoxysilane is greater than 90%.
