| titleOfInvention | Production of indigo |
| abstract | PURPOSE: To produce an indigo in high yields by a very simple process, by reacting an indole with hydrogen peroxide in a liquid phase composed of at least two separate phases of a specified indole-containing organic phase and a hydrogen peroxide-containing water phase. n CONSTITUTION: An indigo is produced by reacting an indole not having any substituents in positions 2 and 3 (e.g., indole, 1-methylindole or 5-nitroindole) with hydrogen peroxide in a liquid phase composed of at least two separated phases of an organic phase containing said indole and a water phase containing hydrogen peroxide. The above process is one which is highly improved as compared with a conventional complicated multistage production process for an indigo, and can produce an indigo in higher yields than the case in which an indole is reacted with hydrogen peroxide in a single homogeneous liquid phase. n COPYRIGHT: (C)1989,JPO&Japio |
