properties | trifluoropropane trimethoxysilane is a colorless liquid at normal temperature and pressure. trifluoropropane trimethoxysilane is a silane reagent and is sensitive to water. it should be kept as dry as possible during storage. |
Use | Trifluoropropane trimethoxysilane can be used to make cross-linked polymers and supramolecular compounds. Under alkaline conditions, the ether bonds are easy to break, and the obtained silanol will undergo intermolecular coupling to obtain macromolecular polymers. In addition, the silicon unit in the structure can also become organic fluorosilicate, which has unique reactivity in coupling reaction and free radical reaction. |
synthesis method | carefully add 3,3, 3-trifluoropropyl trichlorosilane to the high-temperature dry reaction bottle, then add n-hexane to it, stir to make it mix evenly, then slowly add methanol to the reaction system, the obtained mixture is heated to a reflux state, and the reflux reaction is allowed for several hours, the progress of the reaction can be monitored by gas chromatography. After waiting for the reaction to be complete, the n-hexane and unreacted methanol in the reaction system can be removed by rotating evaporation under vacuum, and the resulting residue can be purified by distillation. The target product is trifluoropropane trimethoxysilane. Figure Trifluoropropane trimethoxysilane synthesis route |
