An improved process for the preparation of 10h-phenoxazine |
| abstract |
A process for the preparation of 10H-phenoxazine of the formula (1), which comprises: self condensing 2-aminophenol of the formula (2) condensing 2-aminophenol of the formula (2) with 2-aminophenol of the formula (2) or 2-aminophenol hydrochloride in the presence of iodine and diphenyl ether (as a solvent) wherein the formula (2) and diphenyl ether is used in the ratio of 1 : 1 to 1 : 1.25 with or without additional polar protic high boiling solvent at a temperature in the range of 250 to 280 °C, with or without polar protic high boiling solvent and recovering the resulting 10H-phenoxazine by soxhlet or liquid-liquid extraction. |
