Process for the preparation of hydroxybiphenyls |
| abstract |
The present invention relates to a process for the manufacture of hydroxybiphenyls by hydrolysis of bromobiphenyls at a temperature below 250 ° C in the presence of a catalyst based on copper and an alkaline or alkaline-earth base, characterized in that the concentration of hydroxyl ions is less than 2.5 hydroxyl equivalents per liter of solution. |
