Steps:
1 Example 1 Preparation of Allyltrimethoxysilane
[0020] The apparatus used in this example consisted of a three-neck 100 mL round-bottom flask resting on a heating mantle, a jack having a magnetic stirring bar, an addition funnel, a reflux condenser, a thermometer, and a nitrogen inlet system. [0021] Into the flask was loaded 12.6 gram/0.9 mole of allyldichlorosilane. Into the addition funnel was loaded 8.57 gram/0.26 mole of methyl alcohol. The methyl alcohol was then added to the allyldichlorosilane in the flask drop wise at room temperature. The addition of methyl alcohol to the flask took about 20 minutes to complete. It was observed that the reaction was slightly exothermic. Hydrogen chloride was generated and removed from the flask by sparging with nitrogen. Analysis of the reaction mixture by Gas Chromatography (GC) showed that it contained about a 40 percent GC area percent of allyltrimethoxysilane, with the remainder being unreacted methyl alcohol and 3-methoxypropyltrimethoxysilane CH3O(CH2)3Si(OCH3)3. The presence of allytrimethoxysilane in the reaction mixture was confirmed by Gas Chromatography/Mass Spectrometry (GC/MS) analysis.
