酸性红73制备

1.由对氨基偶氮苯重氮化，再与G盐偶合，盐析而得。1.重氮化将240kg对氨基偶氮苯盐酸盐加入1200L水中，加30%盐酸200kg。搅拌4h，冷至8℃，在3h内从液面下加入30%亚硝酸钠溶液(折100%80公斤)温度不超过15℃，以亚硝酸微过量为终点，保持1h，加冰冷至5℃以下，过滤，滤渣弃去，滤液按体积28%加盐，搅拌20min，过滤，滤饼以水和冰稀释到3000L，温度为0-5℃。2.偶合在桶中放水1500L，纯碱160kg，搅拌，加入G盐270kg，使其全溶。冷至5℃，3h内加入上述重氮液，温度不超过12℃。加毕，测pH应为9，G盐过量。搅拌6h后，升温至60℃，按体积9%加盐，过滤，干燥，得原染料680kg。标准化后得成品染料1000kg。G盐(100%) 280 亚硝酸钠(98%) 82对氨基偶氮苯(100%) 248 盐酸(31%) 196碳酸钠(98%) 157 元明粉160
