NSC 74624 - Reference Information
| chemical properties | white crystal or slightly pink crystal. Melting point 66.5 ℃. Easily soluble in alcohol and ether, slightly soluble in cold petroleum ether, insoluble in water. |
| use | organic synthesis intermediate. |
| production method | is obtained from bromination and chlorination of o-chlorophenol: dissolve o-chlorophenol in carbon tetrachloride, stir and drop bromine below 30 ℃, continue to stir and react for 2 hours after addition, then drive out hydrobromic acid at room temperature, recover carbon tetrachloride and distill under reduced pressure, the 110-120°C (2kPa) fraction was collected to obtain 4-bromo-2-chlorophenol. Dissolve 4-bromo-2-chlorophenol in acetic acid, and pass chlorine gas under cold conditions until crystallization is no longer precipitated. Heat reflux until the crystallization is completely dissolved, decolorization, filtration, cooling crystallization, filtration, washing with petroleum ether to obtain the finished product. |
