application | alkoxy trimethylsilane can be used for the synthesis of silicon organics and can also be used as a water repellent. At present, many related literatures have not been found to report the preparation method of alkoxy trimethylsilane. It is necessary to provide a simple process and high yield of alkoxy trimethylsilane such as isopropoxytrimethylsilane preparation method. |
preparation | isopropoxytrimethylsilane can be prepared from propanol. the specific method is as follows: 1600g of hexamethyldisilazane and 40g and 731 strongly acidic styrene cationic resin are added into a reaction vessel equipped with mechanical stirring, dropping device, tail gas absorption device and strong condensation reflux device, and then nitrogen is introduced into a reaction vessel equipped with a water bath heating system, the temperature is raised to 55 ℃, 1300g of propanol is added dropwise, and the generated ammonia gas enters the tail gas absorption device. In the whole process, the reaction system is slightly positive pressure. After dropping, the reaction is carried out at 50 ℃ ~ 60 ℃ for 5 hours. The conversion rate of hexamethyldisilazane is 100%, and a small amount of propanol remains. After the resin is filtered out, the product content in the reaction solution is higher than 97%, which can be directly used as a finished product. The isopropoxytrimethylsilane product is 25. The yield was 88%. The process is simple, the conversion rate is high, the selectivity is good, the yield is high, and the purity of the final reaction liquid is high. |
Use | Alkoxytrimethylsilane can be used for the synthesis of silicon organics and can also be used as a water repellent. |
emergency measures | if isopropoxytrimethylsilane is inhaled, please move the patient to fresh air. If the skin is in contact with the skin, remove the contaminated clothes, rinse the skin thoroughly with soapy water and clear water, and seek medical treatment if there is discomfort. If the eyes are clear and in contact, the eyelids should be separated, rinsed with flowing water or normal saline, and seek medical treatment immediately; if ingested, gargle immediately, forbid vomiting, should seek medical attention immediately. |
