2,2,2-trifluoro-1-(trifluoromethyl)ethyl methacrylate - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| application | hexafluoroisopropyl methacrylate, transparent colorless liquid. Hexafluoroisopropyl methacrylate is mainly used in synthetic resins and coatings to improve its weather resistance, water resistance and pollution resistance; it is used as a plastic optical fiber skin material, as well as contact lenses and computer toner, and can also be used as medicine, Pesticide intermediates. |
| preparation | 1L four-mouth flask equipped with mechanical stirring, condenser tube (water cooling) and thermometer, add 1.5g of p-methoxyphenol and 60g of 30% fuming sulfuric acid, stir, then add a mixture of methacrylic acid and hexafluoroisopropanol dropwise at room temperature, wherein methyl propylene acid 103g(1.2mol), hexafluoroisopropanol 168g(1mol); The reaction is exothermic, and the dropping time is about 20min. After dropping, the temperature is raised to 94 ℃ for about 3 hours. After the reaction, 217g of hexafluoroisopropyl methacrylate was obtained by simple distillation at normal pressure with a yield of about 92%, and the content of hexafluoroisopropyl methacrylate reached 99.2% without further purification. |
