Versuchsvorschrift
One quarter mole of the alpha-bromoethyltrimethoxysilane (57.3g) is placed in an autoclave along with 17.7g of trimethylamine. The mixture is heated to 80° C. for 6 hours under 200 p.s.i. nitrogen. The excess trimethylamine is allowed to evaporate after the product has been removed from the autoclave, leaving the bromide salt of alpha-trimethylammonioethyltrimethyoxysilane bromide.
