Yield:1067-53-4 99.5%

Reaction Conditions:

with potassium aluminum sulfate at 70 - 80; for 2 h;Reagent/catalyst;

Steps:

1 Example 1
In the presence of magnetic stirring,thermometer,1000ml four-neck flask spherical condenser was charged with vinyltrimethoxysilane148g,Ethylene glycol monomethyl ether 228 g,1g anhydrous potassium aluminum sulfate.Heating up to 70-80 ,Reaction 2h.Then the temperature began to evaporate the methanol,When the kettle temperature rose to 100 ,Methanol recovery is completed,A total of 94 g of methanol was obtained.Then cool down,After cooling to below 50 ° C,filter,And 0.96 g of anhydrous potassium aluminum sulfate was recovered,To obtain 278 g of a colorless transparent vinyl tris- (2-methoxyethoxy) silane product,The yield was 99.5%.The content was 99.5% by gas chromatography.
