| titleOfInvention | Process for the manufacture of naphthostyrile |
| abstract | Process for the preparation of naphthostyril by dissolving 1,8-naphthalimide in an aqueous solution of lithium hydroxide and potassium hydroxide while heating to 40 ° C. to 80 ° C., cooling the solution obtained to 14 ° C. and at this temperature with a maximum of 1 mol percent 1 , 8-naphthalimide sodium, based on 1 mol of 1,8-naphthalimide used, inoculates, then adds chlorine bleach at 10 ° C. to 20 ° C., after the reaction has been carried out, excess active chlorine is reductively eliminated, the resulting aqueous-alkaline solution of the alkali metal salt formed 1-amino-naphthalene-8-carboxylic acid by adding acid to a pH of 2.0 and isolated the resulting naphthostyril. |
