Method of producing 2 4-dihydroxybenzophenone and the derivatives therefrom |
| abstract |
2,4-DIHYDROXYBENZOPHENONE IS PREPARED BY REACTING RESORCINOL WITH BENZOTRICHLORIDE IN A MIXED SOLVENT OF WATER AND A WATER-MISCIBLE ORGAINC SOLVENT SUCH AS A LOWER ALIPHATIC ALCOHOL AT 10* TO 90*C. 2-HYDROXY-4-ALKOXYBNENCOPHENONE IS PREPATED BY REACTIN 2,4-DIHYDROXYBENCOPHENONE, PRODUCED BY THE ABOVE PROCESS, WITH AN ALKYL HALIDE IS SATUREATE KETONE HAVING SIX OR MORE CARBON ATOMS AND CONTAINIING AN ALKALI CARBONATE OR WITH AN ALKYL ESTER OF BENZENESULFONIC ACIDS IN AN AQUEOUS ALKALINE SOLUTION. |
