Versuchsvorschrift

A one liter, three-necked flask equipped with a thermometer, stirring paddle, air tight stirring sleeve, N2 inlet and dropping funnel was charged with aminopropyltrimethoxysilane (100.0 g, 0.558 moles), toluene (160.1 g), sodium methoxide (33.16 g, 0.614 moles) and methanol (10.11 g). The mixture was stirred under N , atmosphere and cooled to 0° C using a dry ice/isopropanol bath. To this, 55.37 g (0.614 moles) of acrylyl chloride dissolved in 100 g of toluene was added gradually over a period of 30 minutes. The mixture was agitated for another 30 minutes. By-product sodium chloride was removed by filtration and the solvent was removed under reduced pressure to obtain acrylamidopropyltrimethoxysilane in essentially quantitative yield. Sodium nitrite (0.001 g) was added as an inhibitor.
