Method and apparatus for preparing 3-[N-(2-aminoethyl)]aminopropylalkoxysilane |
摘要 |
The invention produces a 3-[N-(2-aminoethyl)]aminopropylalkoxysilane in high yields by reacting a 3-chloropropylalkoxysilane with ethylene diamine. A distillation pot is charged with ethylene diamine and heated above the boiling point of ethylene diamine for evaporating ethylene diamine, which is then condensed into a liquid. The liquid ethylene diamine is mixed for reaction with a 3-chloropropylalkoxysilane in such a proportion to give a molar ratio of ethylene diamine/3-chloropropylalkoxysilane of at least 12/1, thereby forming a 3-[N-(2-aminoethyl)]aminopropylalkoxysilane. The reaction solution is fed back to the pot where the unreacted ethylene diamine in the reaction solution is evaporated again and then condensed for use in a next cycle of reaction. The apparatus includes a distillation pot, a reflux condenser, a feed means and a reactor connected to form a recirculating system.
