| titleOfInvention | Manufacture of hydrogenated indoles |
| abstract | Indoles or carbazoles hydrogenated in the nucleus are prepared by electrochemical reduction. Indoles or tetrahydrocarbazoles are electrolysed in aqueous sulphuric acid. The catholyte containing the reaction product is circulated and passed from the electrolytic cell into a column and from the bottom of the column back into the cell. A packed column and flow densities of 1-20 A/dm<2> are preferably used. The catholyte expediently contains 50-70 % by weight strength sulphuric acid. The process products can be used as useful intermediates for dyestuff production. |
