1 EXAMPLE 1
EXAMPLE 1 A 50 ml three necked round bottom flask was equipped with a stirring bar, thermometer, addition funnel and reflux condenser topped with a nitrogen inlet tube. The flask was charged with 12.0 g (0.12 mole) of acetic anhydride. To the dropping funnel was added 6.8 g (0.036 mole) of ethyltris(dimethylamino)silane. The ethyltris(dimethylamino)silane was added dropwise to the acetic anhydride, which had been pre-cooled to 0° C., over a period of two hours, with the temperature of the reaction mixture never being allowed to exceed 20° C. The yield of ethyltriacetoxysilane was determined to be 85% by GC area percent. The material was then distilled under vacuum (74°-75° C./0.7 mm Hg) and showed no evidence of decomposition.
