Reaction Conditions:

at 50 - 60; under 400 Torr;Large scale;

Steps:

1.1 1) Continuous Synthesis of 3-chloropropyltrimethoxysilane:

The chloropropyl trichlorosilane 2100kg and 160kg of methanol,Pre-mixed in the premix tank,After mixing,Spray through the shower to the reaction column,At the bottom of the reaction column,Into 176kg of methanol,Control temperature at 60 ,Methanol was vaporized in the reaction column with the remaining chloropropyltrichlorosilane,The reaction column temperature was controlled at 50 ,The condenser at the top of the column controls the condensation,Prevent the material from being vacuumed away,Vacuum control at 400mmHg,Hydrogen chloride gas generated,Absorption through the tail of the water absorption,As a high concentration of hydrochloric acid as a by-product,Synthetic liquid after distillation to give chloropropyl trimethoxysilane 1900kg, content of 99%;Suggest an edit
