双偶氮黄 G制备

由3，3'-二氯联苯胺重氮化后，与乙酰乙酰苯胺进行偶合，而后经过滤、干燥等处理过程而制产品。1.重氮化2.偶合产品要求色光与标准品近似，着色力为标准品100±5（分），水分含量≤2%，吸油量50±5%，水溶性盐含量≤1.5%，耐热性180℃，耐晒性5-6级，耐酸性、耐碱性均为1-2级，水渗性、油渗性均为1-2级，乙醇渗性1级，石蜡渗性2级，细度（通过60筛余物含量）≤5%。原料消耗（kg/t）3，3'-二氯联苯胺（100%） 410乙酰乙酰苯胺（100%） 590盐酸（31%） 930亚硝酸钠（工业） 235纯碱（工业） 495冰醋酸 615活性炭 10太古油 55方法2:由邻硝基氯苯出发，在烧碱溶液介质中用锌粉还原，并缩合为2，2'- 二氯二苯肼。再用盐酸处理。转位成3，3'二氯联苯胺盐酸盐。而后将3，3'-二氯联苯胺重氮化，再与邻-乙酰乙酰甲苯胺进行偶合，而得到产品。1.还原缩合2.转位、盐析3.重氮化、偶合
