- 粗苯精制产品:噻吩虽可用化学方法合成制取,但成本太高。噻吩存在于煤焦油和页岩油内。用浓硫酸洗涤煤焦油的粗苯馏分所得废酸作原料,在110~150℃水解,然后经分离提纯得到噻吩。噻吩主要存在于粗苯预精馏得到的轻苯中。当轻苯加氢精制时,噻吩遭到破坏,当轻苯酸洗精制时,大部分噻吩与不饱和化合物聚合成焦油状物质,仅有少量噻吩与硫酸作用生成便于提取的噻吩磺酸,这就大大地减少了噻吩的产量。 轻苯酸洗精制时,噻吩与硫酸反应生成噻吩磺酸溶解于废硫酸中,将废硫酸澄清,除去焦油状物质,然后进行水解蒸馏。馏出物经冷凝冷却和分离,可以得到含噻吩和苯族烃的粗馏油。粗馏油经碱中和至中性或微碱性后,用理论塔板数为30~40的精馏塔进行精馏,得到含噻吩大于90%的噻吩产品。精馏时切取的中间馏分集中后回流入粗馏油。当噻吩全部馏出后,残液还可以精馏出含间-二甲苯约95%的间-二甲苯产品。 这种从废硫酸中提取噻吩的方法,粗苯中噻吩的提取率低,且水解蒸馏设备需要使用耐腐蚀材料。为了提高噻吩的提取率,许多国家都在研究从粗苯中提取噻吩的新方法,其中比较成功的是萃取精馏提取噻吩法(ER法)。该法是向含噻吩的苯中加入适宜的萃取剂,以增大苯与噻吩之间的相对挥发度,以便精馏分离出噻吩。在许多萃取剂中,α-吡咯烷酮和N-甲基吡咯烷酮 (NMP)对噻吩的溶解能力强,虽然这种萃取剂只具有中等程度的选择性,但它的化

- 用途四:噻吩(110-02-1)是一种重要的有机化工原料,它的用途非常广泛。主要用于染料、医药和树脂。合成新型广谱抗菌素先锋霉素,是一种重要的医药化工助剂,还可应用于彩色影片制造及特技摄影,合成一种复杂的试剂,用于铀等金属的提取分离等。
- 杂环化合物:噻吩是含一个硫杂原子的五元杂环化合物,在煤焦油制得的粗苯中少量存在,具有类似苯芳香气味的无色液体,沸点为84℃,不溶于水,能与乙醇、乙醚、丙酮、苯、四氯化碳、庚烷、吡啶、1,4-二氧六环等混溶。易燃。耐热性强,加热至850℃而不分解。在强酸条件下不聚合,不分解,也不易被氧化。有中等程度毒性。噻吩环上的5个原子均为sp2杂化,处于同一平面,硫原子的一对未共用电子占据的p轨道与4个碳原子的p轨道平行且重叠,形成5原子6电子的闭合共轭体系,故具有芳香性,噻吩比苯容易发生亲电取代反应,取代主要发生在α-位 (2-位或5-位)。噻吩的重要衍生物是生物素,在室温下可以与浓硫酸发生磺化反应,生产溶于硫酸的2-噻吩磺酸,所以常用这种方法除去粗苯中的噻吩。 噻吩可用于生产各种染料、香料、耐急冷急热塑料、高活性溶剂、刺激素、杀虫剂、增亮剂、化妆品和生物活化物质以及维生素、麻醉剂和抗菌素等药品。也是制备广谱性驱虫药噻嘧啶、抗菌素类药物先锋霉素Ⅰ和Ⅱ的原料,还可进一步制备环丁砜等溶剂。采用化学法或电化学法可合成聚噻吩,经掺杂后,其电导率为2~10.6×103S/m,是一种有潜在应用前景的导电高分子材料。
