| Abstract: | C.I.Acid Yellow 23 was synthesized from p-aminobenzenesulfonic diazo salt and acetylsuccinic acid dimethyl ester by coupling reaction,decarboxylation,cyclization,second coupling reaction and hydrolyzation.The dye purity was 99%,the content was above 90%,the solubility in water was 200 g/L and the application performances were good.The three wastes were reduced by nanofiltration membrane separation technology and the spray drying. |
