| titleOfInvention | A process for the preparation of para-fluorophenol |
| abstract | A method for the preparation of p-fluorophenol by the alkaline hydrolysis of p-bromofluorobenzene in the presence of a copper-containing catalyst at an elevated temperature under pressure, the alkaline agent being a strong base, characterized in that said p-bromofluorobenzene, copper-containing catalyst and strong base are contacted with water where at least the base is gradually added to the reaction zone at an essentially uniform flow rate such that the addition of the base lasts at least the time required to complete the reaction in a batch operation, and less than 12 hours, and the molar ratio of the base is between 1.8 to 3 with respect to said p-bromofluorobenzene. |
