| titleOfInvention | A kind of method producing azoic coupling component AS and recovery and reuse of waste |
| abstract | <b>a kind of method producing azoic coupling component AS and recovery and reuse of waste, including condensation material goes to the step carrying out soda boiling in soda boiling pot, and obtains soda boiling thing and steams thing; Also include the step that described soda boiling thing is carried out vacuum filtration, obtain azoic coupling component AS filter cake and azoic coupling component AS mother solution; The step that described azoic coupling component AS filter cake is dried, obtains azoic coupling component AS; The step that described azoic coupling component AS mother solution is recycled, obtains 2-hydroxyl-3-naphthoic acid; And to the described step steaming and carrying out recycling in thing, obtain nigrosine; The method of Naphthol AS products of the present invention and recovery and reuse of waste, it is possible to reclaim highly purified 2-hydroxyl-3-naphthoic acid from azoic coupling component AS mother solution, improve raw material availability, decrease production cost; Nigrosine can be prepared from steaming recovery thing again, both process industrial wastewater, obtain again new useful pigment; Also improve the quality of Naphthol AS products, add enterprise's productivity effect.</b> |
