3. preparation method:
- tert-butyl(dimethyl)(prop-2-yn-1-yloxy)silane can be prepared by chemical synthesis, the specific steps are as follows:
-Step 1: Use the malodorous gas as the solvent, and introduce the gas into the reactor through the pipeline;
-Step 2: A Zhan-blown acid treatment agent generates silver ions from silver compounds, and in the presence of silver ions, an acid-catalyzed acetylenic silver addition reaction occurs with acetylenic alcohols to generate acetylenic hydrocarbons;
-step 3: catalytically adding the alkyne obtained in step 2 to tert-butanol to generate propargyl alcohol;
-Step 4: Use aluminum-lithium alloy to reduce propargyl alcohol to propargyl hydrocarbon;
-Step 5: React propargyl with dimethylchlorosilane through silicon chemical reaction to obtain the final product tert-butyl(dimethyl)(prop-2-yn-1-yloxy)silane.
4. Safety Information:
- tert-butyl(dimethyl)(prop-2-yn-1-yloxy)silane is relatively stable and is not prone to fire or explosion under normal use conditions.
-but it may be irritating and corrosive to the eyes and skin, use should wear personal protective equipment, such as glasses and gloves.
-Avoid inhaling its vapors or contacting its liquids to avoid discomfort or damage to health.
-In use or storage, should comply with the relevant safety guidelines and regulations.
