Continuous production reaction device and continuous production reaction method for N-(beta-aminoethyl)-gamma-aminopropyltrimethoxysilane

The invention discloses a continuous production reaction device and a continuous production reaction method for N-(beta-aminoethyl)-gamma-aminopropyltrimethoxysilane, which belong to the technical field of silane coupling agents. The invention designs a tower-type continuous reaction device, wherein a mixed solution of ethylenediamine and chloropropyl trimethoxysilane, which is sprayed downwards from the top of a reaction tower (2) finishes reaction in a falling process in the reaction tower (2) under the excessive protection of ascending ethylenediamine vaporization liquid, and is automatically pumped into a continuous sedimentation liquid separator by a material transfer pump (12) for automatically controlling the amount of a reaction liquid in a reaction kettle (3) to perform continuous liquid separation; the obtained clear liquid is rectified to obtain N-(beta-aminoethyl)-gamma-aminopropyltrimethoxysilane. The device disclosed by the invention is matched with the process, and continuous reaction and continuous liquid separation can be performed to realize production; the consumption of ethylenediamine is effectively reduced, and both purity and yield are high; the production efficiency is improved while the reaction continuity is ensured, and no ethylenediamine hydrochloride in the separated clear liquid can also be ensured.
