Filed: 1980-06-10
Abstract: PURPOSE: To obtain the titled compound continuously at a low cost readily, by subjecting a uniform mixture prepared by kneading a wet cake of a partial alkaline salt of a specific trisulfonic acid with an adequate amount of an alkali to the alkali fusion.  
     CONSTITUTION: A wet cake of a partial alkaline salt of 1-aminonaphthalene-3,6,8- trisulfonic acid is kneaded with part or all of an alkali necessaey for the neutralization of the wet cake and alkali fusion reaction in a mixing kneader or kneader. The resultant uniform mixture having the fluidity is subjected to the alkali fusion to give 1-amino-8-naphthol-3,6-disulfonic acid. In case part of the alkali is used, the remaining alkali is added to the uniform mixture before the alkali fusion.  
     EFFECT: A readily handleable molten raw material with fluidity permits the process in one stage. The energy can be saved, and the method is advantageous to cost due to the 50% alkaline solution used.
