2.对环境的影响
一、健康危害
侵入途径:吸入、食入。
健康危害:本品对眼和上呼吸道有刺激性。对中枢神经有抑制作用,致肝、肾损害。人在接触高浓度时,可表现虚弱、眩晕、呕吐。严重时损害肝脏,出现黄疸,肝损害可发展为肝坏死或肝硬化。长时间抵触本品对皮肤有轻微刺激必,引起烧灼感。
二、毒理学资料及环境行为
急性毒性:LD 50500mg/kg(大鼠经口)
亚急性和慢性毒性:大鼠、豚鼠和兔接触5.23g/m 3,69次,见颤、虚弱、减重、眼刺激和毛蓬乱,肝肾发生病理改变。
致突变性:姊妹染然单体交换:人类淋巴细胞100ug/L。精子形态学:大鼠腹腔800mg/kg。
生殖毒性:大鼠经口最低中毒剂量(TDL 0):7500mg/kg(孕6~15天用药),引起肌肉骨骼发育异常。
致癌性:IARC致辞癌性评论:对人可能致癌。
污染来源:1,4-二氯苯污染物来源于生产抗蛀剂、空气脱臭剂、染料、药剂、土壤消毒剂、酚、氯代硝基苯等车间或工厂。
由于1,4-二氯苯具有升华作用,通常在水和土壤中的1,4-二氯苯会较快的挥发到空气中。因此,受1,4-二氯苯污染的水和土壤能较快地得到恢复。
该物质对环境有危害,对水体和大气可造成污染,在对人类重要食物链中,特别是在水生生物中可发生生物蓄积。
危险特性:可燃。遇明火能燃烧。受高热分解产生有毒的腐蚀性烟气。与强氧化剂接触可发生化学反应。与活性金属粉末(如镁、铝等)能发生反应,引起分解。
燃烧(分解)产物:一氧化碳、二氧化碳、氯化氢。

6.应急处理处置方法


一、泄漏应急处理
隔离泄漏污染区,限制出入。切断火源。建议应急处理人员戴自给正压式呼吸器,穿防毒服。不要直接接触泄漏物。1,4-二氯苯为固体,易升华。1,4-二氯苯如洒落在土壤或地面上,可直接收入密封的金属容器或低袋中,或倒到空旷地方掩埋,或作为废弃物进行焚烧;1,4-二氯苯如洒落在水中,可筑防护堤;洒落在空旷地方的1,4-二氯苯可就地掩埋。
二、防护措施
呼吸系统防护:可能接触其毒物时,必须佩戴自吸过滤式防毒面具(半面罩)。紧急事态抢救或撤离时,佩戴自给式呼吸器。
眼睛防护:戴安全防护眼镜。
身体防护:穿防毒物渗透工作服。
手防护:戴橡胶手套。
其它:工作现场禁止吸烟、进食和饮水。工作毕,沐浴更衣。单独存放被毒物污染的衣服。洗后备用。注意个人清洁卫生。
三、急救措施
皮肤接触:脱去被污染的衣着,用肥皂水和清水彻底冲洗皮肤。就医。
眼睛接触:提起眼睑,用流动清水或生理盐水冲洗。就医。
吸入:迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难,给输氧。如呼吸停止,立即进行人工呼吸。就医。
食入:饮足量温水,催吐,就医。
灭火方法:雾状水、泡沫、二氧化碳、砂土、干粉。

苯定向氯化或从氯苯生产中回收。

1.苯定向氯化将苯置于氯化反应器中,加苯重量的0.1%-0.6%的硫化锑,通入氯气,控制氯化温度在20℃左右,氯化30-45分钟,加入苯磺酸定向催化剂,然后再通入氯气,当二氯苯晶体析出时,将反应液加热到50-60℃,再缓速通氯气直到反应液增重理论量的95%左右为止,收率70%-75%。由于苯氯化产物组分较多,工业制备的关键是对二氯苯选择适当的分离,精制方法。分离和精制对、邻位二氯苯的方法较多。精馏法较结晶法难度大、能耗高,不利于产物的稳定和设备的防腐蚀。重结晶法已发展到连续分级结晶法。乳化法利用表面活性物质进行乳化而分离,此法具有操作简单,能耗低,效率高和环境污染少等优点,对其研究日见增多,发展较快。

2.由氯苯生产过程中回收将氯苯精馏塔底物,经真空蒸馏蒸出混合二氯苯,在结晶器中进行结晶而得较纯的对二氯苯。
