Paragraph 0045; 0046, (2019/04/10)
The invention belongs to the technical field of a fluorine-containing material, and particularly relates to a method for synthesizing a flurosilicon compound by using a continuous flow microreactor. The synthesis method is characterized in that the continuous flow microreactor is used as a reaction device; the method comprises the following steps of (1) flowing fluoroolefin, alkoxy silane and catalysts dissolved into organic solvents into a mixed reaction module M with the preset temperature T for mixed reaction respectively through metering pumps P1, P2 and P3 via a material passage A, a material passage B and a material passage C; (2) after the mixed reaction is completed, flowing reaction liquid flows out of an outlet D; performing post treatment by flow-out reaction liquid to obtain the flurosilicon compound. The synthesis method provided by the invention has the advantages of scientificalness, reasonableness, simplicity and easy implementation. The problems of serious heat release, difficult operation control, rigorous equipment requirement, low yield, long reaction time and the like in the existing chlorsilane silicon and hydrogen addition can be solved.

Four silane coupling agents, (1H,1H,2H,2H-polyfluoroalkyl)trimethoxysilanes ((1H,1H,2H,2H-henicosafluorododecyl)trimethoxysilane, C10F21C2H4Si(OCH3)3, (1H,1H,2H,2H-heptadecafluorodecyl)trimethoxysilane, C58F17C2H4Si(OCH3)3, (1H,1H,2H,2H-tridecafluorooctyl)trimethoxysilane, C6F13C2H4Si(OCH3)3, and (1H,1H,2H,2H-nonafluorohexyl)trimethoxysilane, C4F9C2H4Si(OCH3)3), were prepared by the hydrosilylation of trichlorosilane with the corresponding 1H,1H,2H,-polyfluoro-1-alkene in the presence of hydrogen hexachloroplatinate-(IV), followed by reaction with sodium methoxide.The surface modification of glass plate was attempted using these products.From measurements of the contact angles θ (deg) of water and oleic acid against a modified glass plate surface, the coupling agents were found to have high modification ability.The modification produced a glass surface with high oxidation resistance.
