After use, the residue should not be disposed of at will. When in accordance with relevant regulations, properly dispose of to avoid polluting the environment.
What are the synthesis methods of 1,2-bis (trimethoxysilyl) ethane?
1% 2C2-bis (trimethoxysilyl) ethyl ketone. The synthesis method of this substance is as follows:
First, trimethoxysilane and acetylene are used as starting materials, and the hydrosilylation reaction of the two occurs under the action of a catalyst. This reaction requires a suitable catalyst, such as a platinum catalyst, to be carried out under appropriate temperature and pressure conditions. The silica-hydrogen bond of trimethoxysilane and the carbon-carbon triple bond of acetylene are added to form vinyltrimethoxysilane.
Then, vinyltrimethoxysilane is hydroformylated with carbon monoxide and hydrogen under the action of a specific catalyst system. This step also requires careful selection of catalysts, such as rhodium-based catalysts, and precise regulation of the temperature, pressure, and ratio of reactants. Through hydroformylation, an aldehyde group is introduced into the double bonds of vinyltrimethoxysilane to form formylethyltrimethoxysilane.
Finally, formylethyltrimethoxysilane is oxidized. Under suitable reaction conditions, the formyl group is oxidized to ketone carbonyl, resulting in the target product 1% 2C2-bis (trimethoxysilyl) ethyl ketone.
Each step of the reaction requires strict control of the reaction conditions, such as temperature, pressure, catalyst dosage, reactant ratio, etc., and side reactions in the reaction process should be properly handled to improve the purity and yield of the product. In this way, 1% 2C2 -bis (trimethoxysilyl) ethyl ketone can be effectively synthesized.
