Summary:
the invention discloses a synthesis method of 1,4 diaminoanthraquinone and its leuco, adding 1,4 dihydroxyanthraquinone, sodium hydroxide, sodium hydrosulfite and ammonia solution to a high-pressure reaction kettle, sealing the autoclave, stirring evenly, heating to 8595 ℃, holding the reaction for several hours, then cooling to 4050 ℃, discharging the material under pressure, washing with hot water to PH 78, and drying. The invention adds sodium hydroxide and sodium hydroxide when feeding, so as to give full play to the reducing effect of the sodium hydroxide. While improving product quality, it reduces the cost pressure caused by the treatment of three wastes. The purity of the obtained 1,4 diaminoanthraquinone and its leuco products is increased from 90% to 95%, the yield is increased from 80% to 88%, and the obtained ammonia nitrogen wastewater is halved, which reduces the cost of ammonia nitrogen wastewater; this process does not use organic solvents, while reducing the use of ammonia water, reducing the cost of recycling and processing organic solvents.
