Preparation method of perfluorohexylethyl sulfonate

The present invention relates to the technical field of fluorocarbon surfactants, and discloses a preparation method of perfluorohexylethyl sulfonate. The preparation method comprises: S1, dissolving sodium hydrosulfide in absolute ethyl alcohol, adding perfluorohexylethyl iodide and a catalyst, and carrying out a reaction under a heating condition to obtain perfluorohexyl ethanethiol; S2, blending perfluorohexyl ethanethiol and nitric acid, and reacting under a heating condition to obtain perfluorohexylethyl sulfonic acid; and S3, reacting the perfluorohexylethyl sulfonic acid with an alkali, purifying, and drying to obtain the perfluorohexylethyl sulfonate. According to the preparation method, perfluorohexylethyl iodide is used as a raw material, and absolute ethyl alcohol is used as a solvent. The method can reduce the production cost, digest production waste, and is safe, environment-friendly and simple to operate.

FLUOROSILANES

Fluoroalkyl silanes are a class of compounds useful for various industrial purposes. For example, fluoroalkyl silanes which have hydrolysable groups (called hydrolysable fluoroalkyl silanes), are compounds useful as surface treatment agents which provide durable hydrophobic and oleophobic coatings. In general, hydrolysable fluoroalkyl silanes can be represented with the following formula: (RO—)3Si—RT wherein R is H or an alkyl; and RT is a monovalent organic compound terminated by a perfluoroalkyl group. When used to coat a surface, the (RO—)3 moiety reacts (via hydrolysis) with various chemical groups of the surface (e.g., hydroxyl, amine, or other reactive groups) thereby bonding the fluoroalkyl silane to the surface The RT moiety comprises a divalent organic linking group which links the silicon atom to a terminal group rich in fluorine atoms whose unique electronic properties impart desirable hydrophobic and oleophobic properties in a surface coating. Modification of the RT moiety is useful in the engineering of fluoroalkyl silanes. The present invention provides for fluoroalkyl silanes having RT moieties which have not been heretofore considered.

Novel fluorinated amphiphilic cyclodextrin derivatives: Synthesis of mono-, di- and heptakis-(6-deoxy-6-perfluoroalkylthio)-β-cyclodextrins

A new series of fluorinated amphiphilic β-cyclodextrin derivatives has been synthesized. The strategy is based on the modification of the C-6 position of the mono-6-deoxy-6A-para-tolylsulfonyl, di-6A, 6D-deoxy-6A, 6D-(para-tolylsulfonyl) and heptakis-(6-deoxy-6-iodo)-β-cyclodextrin precursors. The synthesis lead to mono-perfluoroalkylthio-, di-perfluoroalkylthio- and heptakis-perfluoroalkylthio-β-cyclodextrin in excellent yields (90-99%).
