Abstract

The invention relates to a novel amination process of amino silane, which is characterized in that the bottom of a reaction tower A is communicated with an inlet of a coiled pipe B; an outlet of the coiled pipe B is communicated with an upper feed port of a product receiving device C; the bottom of the product receiving device C is provided with a discharge port P; the upper part of the product receiving device C is also communicated with the bottom end of a gas raising pipe D; the upper end of the gas raising pipe D is communicated with the top of the reaction tower A through a reflux feed inlet G of a condenser H; and the upper part of the reaction tower A is sequentially provided with a first feed inlet E and a second feed inlet F. The new amination process of the amino silane comprises the following steps of: uniformly adding quadrol at the speed of 1530-2000 g / 5h; and uniformly adding gamma-chloropropyl methyl dimethoxy silane at the speed of 1000 g / 5h to complete amination so as to obtain a final product. The invention designs a novel device matched with the good process and has the advantages of high product yield, reasonable and compact device, stable operation and continuous reaction.

Description

technical field [0001] The invention relates to an amination process in the chemical field, in particular to a novel aminosilane amination process. Background technique [0002] γ-Chloropropylmethyldimethoxysilane is a by-product of the applicant in other production processes, and has never been used properly. [0003] For a long time, the follow-up amination treatment of γ-chloropropylmethyldimethoxysilane is mostly a batch reaction, and the reaction efficiency is low. γ-Chloropropylmethyldimethoxysilane is used for subsequent amination treatment, the reaction device is complicated, and the equipment investment is high. Contents of the invention [0004] The purpose of the present invention is to provide a new process for aminosilane amination. [0005] The problem solved by the present invention is to perform subsequent amination treatment on γ-chloropropylmethyldimethoxysilane so as to obtain aminosilanes. [0006] The invention designs a new device with a good proce...
