Folks,
I've seen some references in the literature for functionalizing glass
surfaces with amine groups using Ethanolamine hydrochloride (instead
of using silanes).

To answer your question, you should probably use ethanolamine.

But try vapor phase silanization. It's much easier to control than
silanizing from solvent solution where some silanes hasten to turn
into chewing gum. A Teflon reaction bomb works well, so you can raise
the temperature for less-volatile silanes.

If your silane is trifunctional, as in trimethoxy or trichloro, you
can bake the monolayer after vapor deposition, to form the
crosslinks.
