硝基苯上游产品

硝基苯下游产品

1.由苯经混酸硝化而得。这是生产硝基苯的传统方法，最初采用间歇法生产，后来发展了连续法，近来又发展为绝热硝化法。间歇法是苯和混酸的铸铁硝化锅中于50℃下反应。连续硝化采用串联的硝化器，为使硝酸是到充分利用，并减少二硝基苯的生成，加入的苯稍过量。连续法的优点是生产能力大，硝酸的浓度可适当降低。绝热硝化法可间歇或连续操作，反应热可利用来浓缩硫酸，副产物二硝基苯较少。原料消耗定额：纯苯（工业品）665kg/t、硝酸（98%570kg/t、硫酸（92.5%）50kg/t、纯碱20kg/t。

2.精制方法：硝基苯通常含有硝基甲苯、二硝基噻酚、二硝基苯和苯胺等杂质。精制时用稀硫酸、稀碱和水依次洗涤，氯化钙干燥后反复进行减压蒸馏。也可以用分步结晶或用绝对乙醇重结晶的方法精制。其他的精制方法有：在稀硫酸存在下进行水蒸气蒸馏，馏出物分去水层后，用氯化钙干燥，然后在氧化钡、五氧化二磷三氯化铝或活性氧化铝存在下减压蒸馏。

3.以工业硝基苯为原料，加入无水氯化钙干燥脱去水分，然后进行蒸馏收集208.5～212.0℃馏分，即得成品。也可采用减压蒸馏，操作压力为267Pa。
