Preparation of certain m-aminophenols and the use thereof for preparation of laser dyes
Patent
·
OSTI ID:866053
- Livermore, CA
Methods are provided for making certain m-aminophenols using a sulfonation/alkali fusion procedure. The aminophenols are key intermediates in the synthesis of dyes, particularly efficient, stable dyes for laser application. Preparations of some rhodamine and phenoxazone dyes from the m-aminophenols are described.
