Method for synthesizing flurosilicon compound by using continuous flow microreactor

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.

PERFLUORO-ALKYL MODIFIED ORGANIC SILANE

The present invention relates to a method for preparing perfluoroalkyl modified organic silane, and the method for preparing perfluoroalkyl modified organic silane comprises a step for adding a pyrolytic radical initiator and a tin-based organic metal compound to a mixture of a perfluoroalkyl iodide compound and an organic silane having a double bond. The method for preparing perfluoroalkyl modified organic silane suppresses an additive reaction of the pyrolytic radical initiator and smoothens the reduction of iodine, thereby forming perfluoroalkylalkoxy silane at high efficiency and high purity, causes no chlorine gas, which is a toxic gas, thereby making less environmental loading, such as gas purification facilities, and does not use an expensive metal catalyst and hydrogen gas, thereby preparing perfluoroalkyl modified organic silane easily and economically.COPYRIGHT KIPO 2016

Syntheses and Reactions of Metal Organics. XVIII. Syntheses of (1H,1H,2H,2H-Polyfluoroalkyl)trimethoxysilanes and Surface Modification of Glass Plate

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.
