酸性蓝 74制备

1.靛蓝制备
食用靛蓝实际上是靛蓝二磺酸二钠，由靛蓝用浓硫酸磺化，磺化结束后用水稀释，再用纯碱中和，最后加入氯化钠盐析，经过滤、水洗、干燥得成品。靛蓝铝色淀制备
由氯化铝、硫酸铝等的铝盐与碳酸钠等的碱类制取氢氧化铝，然后添加于靛蓝水溶液，沉淀而得产品。

2.用浓硫酸或与少量发烟硫酸合用，使靛蓝。磺化后，用水适量稀释，经碳酸钠或氢氧化钠中和，以硫酸钠或氯化钠盐析，再经精制而得。由靛蓝粉经浓硫酸磺化后，加水稀释，用碳酸钠中和，再经盐析，精制而得。每吨产品消耗靛蓝粉（100%）210kg。由双二甲基氨基二苯基甲醇与2-羟基萘-3，6-二磺酸，于浓硫酸存在下，失去一分子水缩合成无色母体，在弱酸溶液中用二氧化锰氧化成三芳基甲烷色素。
二苯基甲醇系由二氧化锰和硫酸氧化四烷基二氨基二苯基甲烷而得。可直接使用其离心分离的滤饼进行缩合。二氧化锰系由硫酸锰与高锰酸钾在碳酸钠溶液中新鲜制备而得。
