Abstract
Gravimetric and infrared spectroscopic observations of n-butylamine adsorption onto silica have shown that strong adsorption is associated primarily with isolated surface hydroxyl groups and also with some vicinal surface groups. Adsorbed material can be totally removed from the surface by outgassing at elevated temperature (to 200 °C) without irreversible changes to the underlying surface. The interaction between adsorbed amine and ethylene oxide vapor has been investigated and a possible reaction mechanism is presented.Keywords
