1,2-二溴乙烷 制备方法及用途

合成制备方法

1.乙烯溴化法 工业生产采用乙烯与溴进行非催化加成,反应速度随反应温度升高而增加,水蒸气的存在能加速反应的进行。排放尾气中含过剩乙烯和HBr,经洗涤塔用水洗涤脱HBr,再回收过剩乙烯。

2.乙烷溴化法。

3.乙二醇和溴氢酸反应法。

用途

1.用作溶剂,用于有机合成、杀虫剂、医药等。用作汽车、航空燃料添加剂,赛璐珞的不燃性溶剂,谷物、水果的杀菌剂以及木材的杀虫剂等。

2.用作溶剂,用于有机合成,制造杀虫剂、药品等。[26]

稳定性相关:

1.在光作用下部分发生分解。与强碱反应生成溴代乙烯。

2.蒸气有毒,浓度高时能引起麻醉作用,全麻时会引起肺水肿致死。空气中最低中毒浓度25×10-6。吸入致死浓度1000×10-6。对啮齿动物有致癌作用。空气中最高容许浓度130×10-9。蒸气刺激呼吸道,损伤肝、肾。液体接触皮肤可致溃烂。受到沾污时,应立即脱去外衣,擦干皮肤。生产场所要求通风良好,备有防毒面具和防护服等。

3.具有中度麻醉作用,易被皮肤吸收,其蒸气刺激眼黏膜和上呼吸道。麻醉性小,但能引起感觉迟钝、抑郁、呕吐。服用40g即可致死。慢性中毒时,能引起眼球结膜炎、支气管炎、喉头炎、食欲不振、抑郁等症状。潜在致癌物。嗅觉阈浓度199.94mg/m3。工作场所最高容许浓度为192.25 mg/m3。

6、应急处理处置方法


一、泄漏应急处理
迅速撤离泄漏污染区人员至安全区,并立即隔离150米,严格限制出入。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。尽可能切断泄漏源,防止进入下水道、排洪沟等限制性空间。小量泄漏:用砂土、蛭石或其它惰性材料吸收。大量泄漏:构筑围堤或挖坑收容。用泡沫覆盖,降低蒸气灾害。用泵转移至槽车或专用收集器内,回收或运至废物处理场所处置。
废弃物处置方法:用控制焚烧法,焚烧系统要按装洗涤器和贮灰装
