An oil-water separation apparatus is provided which can easily separate and collect oil from a liquid mixture containing water and oil at low cost. The oil-water separation apparatus includes an oil-water-separating member configured to separate a liquid mixture containing water and oil into moisture and oil, and a liquid reservoir subdivided into an upper region and a lower region by the oil-water-separating member. The oil-water separation apparatus filters the liquid mixture by gravity. The oil-water-separating member includes a base which includes a channel for the liquid mixture. The oil-water-separating member is formed in the base, and the oil-water-separating member contains a fluorine compound which has an oil-repellency-imparting group and a hydrophilicity-imparting group. A drain port for discharging the moisture is formed in the lower region of the liquid reservoir.

The filter medium is a filter medium which uses a liquid containing oil and water as a separation target, and has a channel for the liquid. The filter medium includes a base constituting the channel, and one or more of nitrogen-containing fluorine compounds which are provided on at least a portion of a surface of the channel. The nitrogen-containing fluorine compound includes an oil-repellency imparting group and any one hydrophilicity imparting group selected from a group consisting of an anion type, a cation type, and an amphoteric type, in a molecule.

A novel fluorine-containing silane compound is provided. The fluorine-containing silane compound is capable of providing excellent water repellency and oil repellency, and is useful as a fluorine-containing silane coupling agent with applicability to a wide variety of applications, even if it has a chemical structure, which is free of a perfluoroalkyl group of 8 or more of carbon atoms; and has no risk of formation of PFOS or PFOA causing bioaccumulation potential and environment adaptability problems. A fluorine-containing silane compound containing at least one of each of a nitrogen-containing perfluoroalkyl group and an alkoxysilyl group in the molecule is selected.

Fluorine-containing silane compound

According to the method for producing fluorine-containing N-alkylsulfonylimide compound, the fluorine-containing N-alkylsulfonylimide compound can be produced safely with a high recovery rate by alkylating fluorine-containing sulfonylimide acid or fluorine-containing sulfonylimide acid salt with dialkylsulfuric acid or dialkylcarbonic acid.
