| titleOfInvention | Synthetic method of 4,4, 4-trifluoro-2-butenol |
| abstract | The invention discloses a method for synthesizing 4,4, 4-trifluoro-2-butenol, which comprises the following steps: putting anhydrous methanol and an initiator into a reactor with illumination, replacing a system by N2, slowly introducing 1-X-3,3, 3-trifluoropropene under the illumination of light, and keeping the temperature until the reaction is complete after the introduction of the 1-X-3,3, 3-trifluoropropene; most of the methanol is evaporated under reduced pressure, and the concentrated solution is rectified to obtain 2-X-4,4, 4-trifluorobutanol; putting prepared 2-X-4,4, 4-trifluorobutanol into a reaction kettle, diluting with a solvent, adding a catalyst and a polymerization inhibitor, and adding alkali to remove HX; the 4,4, 4-trifluoro-2-butenol is obtained by layering, extraction, drying and concentration. The process has the advantages of low cost of raw materials, mild reaction conditions and high yield of over 80 percent. |
