联苯胺

联苯胺用途

【用途一】
重要的染料中间体，联苯胺及其衍生物可用于制造直接染料、酸性染料、还原染料、冰染染料、硫化染料、活性染料及有机颜料。由联苯胺制成的染料约有250种以上，其中最重要的是直接黑EW，联苯胺黄为广泛应用的一种有机颜料。
【用途二】
比色法测定各种氧化剂，氧化性金属、氰化物和血液的检定。硫酸盐、钨酸盐、磷酸盐和糖分的测定。氧化还原指示剂。用于偶氮染料中间体，也作不溶偶氮染料的显色剂。
【用途三】
用于偶氮染料中间体，也作不溶偶氮染料的显色剂。用于ICP-AES、AAS、AFS、ICP-MS、离子色谱等。滴定分析用标准溶液。

联苯胺下游产品

联苯胺制备

1.由硝基苯还原生成氢化偶氮苯，再经重排而得。工业生产中，氢化偶氮苯重排经由联苯胺盐酸盐，再加浓硫酸得到联苯胺硫酸盐。

2.硝基苯在碱溶液用锌粉还原为对称二苯肼，再在盐酸介质中分子重排为盐酸联苯胺，然后加入液碱使其成游离基即可。

3. 将200kg硝基苯与180kg13%的氢氧化钠溶液混合，边搅拌边加热至95℃，分批少量加入锌糊 （锌粉∶水＝1∶1） ，加锌过程中控制反应温度在100～105℃，加完后将温度降至90～95℃，并维持该温度下，再加入锌糊，至反应液呈淡黄色或无色，反应达终点。然后将反应液温度降至3～7℃，在4.5h内以先快后慢速度喷入雾状的30%的浓盐酸至ph 值为5.8，过滤，滤液回收锌盐，所得粗二苯肼结晶用50%乙醇洗涤至中性，再用乙醇重结晶提纯，提纯后的二苯肼慢慢加到事先冷至0℃的300L30%的盐酸和400kg碎冰的混合物中，加完后搅拌至完全溶解，再加水使总体积达4500L，加热至95～97℃，回流2h，趁热过滤，滤液冷却，用稍过量的40%的氢氧化钠溶液中和，即有联苯胺析出，过滤后，用水洗涤结晶并用水重结晶提纯，即为成品联苯胺。
