Overview | perfluoroalkyl ethyl (meth) acrylate is an important fluorinated chemical, its polymer has excellent oil resistance and water resistance, is an important intermediate for the production of surface protective agents, and is widely used in textile, coating and fluorinated surfactant fields. However, perfluorooctanoic acid (PFOA) is difficult to be excreted in vitro because of its biological accumulation and persistence, and (meth) acrylate or its polymer containing perfluorooctyl (C8) is decomposed, oxidation, etc., and finally PFOA was generated. |
Introduction | 3,3,4,4,5,5,6,6,7,7,8,8, 8-trifluoro-1-octanol, also known as perfluorohexyl ethanol, is a perfluoroalkyl ethanol. Perfluoroalkyl ethanol is an important intermediate for the synthesis of perfluoroalkyl surfactants and functional materials, because of its unique chemical stability, corrosion resistance, flame retardant, hydrophobic and oleophobic, antifouling and so on are widely used in textile, military, electronics, aerospace, anti-corrosion, chemical and other fields, and its preparation method is a research hotspot in recent years. |
Use | perfluorohexyl ethyl alcohol is an intermediate for the preparation of perfluorohexyl ethyl acrylate. perfluorohexylethyl alcohol is a material used to improve nanotube composites. It can also be used in the synthesis of recycled fluorhydrazino thiosulfate compounds with NCS to catalyze the acetalization of aldehydes. |
prepare | A 5L glass reaction bottle with Condenser tube, magnetic stirrer and thermometer, 474G of perfluorohexyl ethyl iodide (C6F13CH2CH2I) was added, 2370g of mixed solvent (nmp1896 G, DMSO 474g), and 108g of water. The reaction was stirred and heated to 160 ℃ for 18H. Gas phase detection also contained perfluorohexyl ethyl iodide 1.8%, 4,5,5,6,6,7,7,8,8, 8-tridecafluoro-1-octanol, conversion rate 99.3%, yield 96.0%, gas chromatography purity 99.4%. |
