| titleOfInvention | The preparation method of the chloro-6-fluorophenol of a kind of 2- |
| abstract | The invention discloses the preparation method of the chloro-6-fluorophenol of a kind of 2-, comprise the following steps: (1) add adjacent fluorophenol in the reactor, slowly aqueous sodium hypochlorite solution is dripped in reactor, the mol ratio of clorox and adjacent fluorophenol is (1.0 ~ 2.0): 1, reactor is warming up to 0 ~ 77 DEG C, insulation reaction, generates the mixture of the chloro-6-fluorophenol of 2-; (2) after reaction terminates, in reactor, add dilute hydrochloric acid, regulate pH to be 5 ~ 6.5, leave standstill and separate organic phase; (3) organic phase purification drying step (2) separated obtains the chloro-6-fluorophenol of 2-.Above-mentioned preparation method, simple to operate, cost is low, can industrial mass operation produce. |
