  • 储运特性:库房通风低温干燥; 与氧化剂、食品添加剂分
  • 方法一:1.乙烯法本法可联产三氯乙烯和四氯乙烯，分下列二法。a.直接氯化乙烯和氯在含FeCl3催化剂的1,2-二氯乙烷溶液中，于280-450℃进行反应，生成1,2-二氯乙烷，再进一步氯化成三氯乙烯和四氯乙烯，经蒸馏后，分别用NH3中和、洗涤、干燥，即得成品。b.氧氯化法以乙烯和氯加成生成1,2-二氯乙烷，1,2-二氯乙烷与氯、氧在以CuCl2和KCl为催化剂以及425℃、138-207kPa条件下进行氧氯化反应，产物经冷却、水洗、干燥后蒸馏，得高纯度产品。2.烃类氧化法将含甲烷、乙烷、丙烷、丙烯等的烃类混合物于50-500℃氯化热解，得氯代烃类的混合物，精馏后分离成各种产品。3.乙炔法乙炔和氯加热氯化生成1,1,2,2-四氯乙烷，用碱脱去氯化氢得三氯乙烯，再经氯化生成五氯乙烷，然后再用碱脱去氯化氢得四氯乙烯。因乙炔价昂，已逐步为乙烯法等代替。
  • 测定方法:在空气中的测定： 用活性炭吸附，CS2处理，气相色谱法分析。 在水中的测定： 先用惰性气体清洗，继之以卤化物特异性检测的气相色谱法或气相-质谱联用法分析。
  • 刺激数据:皮肤-兔子810 毫克/24小时 重度；眼睛-兔子 500 毫克/24小时 轻度
  • 类别:农药
  • MOL 文件:127-18-4.mol
  • 四氯乙烯价格(试剂级):更新日期 产品编号 产品名称 包装 价格 2011/08/23 LB2008901 四氯乙烯;过氯乙烯 500ml 332元 2011/08/23 80123318 四氯乙烯;过氯乙烯 500ml 38元 2011/08/23 80123328 四氯乙烯;过氯乙烯 500ml 31元
  • 蒸气压:13 mm Hg ( 20 °C)
  • 外观性质:无色液体，有氯仿样气味。
  • 防护措施:有毒，是中枢神经抑制剂，吸入、吞咽或经皮肤吸收都能引起强烈的危害，如头痛、颤抖、呕吐，严重时失去知觉终至死亡。对眼睛和皮肤有刺激性。接触时，应立即用水清洗。空气中最高容许浓度0.0001。
  • Sigma Aldrich:127-18-4(sigmaaldrich)
  • 用途四:有机分析中用作脂肪或脂肪类似物质的溶剂。高压液 相色谱试剂。分光光度测定用溶剂。有机合成。
  • 有害影响和中毒症状:反复接触四氯乙烯液体能引起皮肤干裂和皮炎。高浓度蒸气能刺激眼和鼻。 急性暴露于较高浓度四氯乙烯中，能引起中枢神经系统
  • 上游原料:氯 --> 1,2-二氯乙烷 --> 三氯乙烯 --> 氘代四氯乙烷 --> 五氯乙烷 --> 碱脱
  • 用途与作用:工业上四氯乙烯主要用作溶剂、有机合成、金属表面清洁剂和干洗剂、脱硫剂、热传递介质。医疗上用作驱虫药。也是制三氯乙烯和含氟有机物的中间体。一般居民通过大气、食品及饮水可能接触低浓度的四氯乙烯。 四氯乙烯对许多无机和有机化合有良好的溶解能力，如硫、碘、氯化汞、三氯化铝、脂肪、橡胶和树脂等，这种溶解能力被广泛用作金属脱脂清洗剂、脱漆剂、干洗剂、橡胶溶剂、油墨溶剂、液体皂，高档毛皮及羽毛的脱脂；四氯乙烯也用作驱虫(钩虫和姜片虫)药；纺织品加工整理剂。 四氯乙烯也是一种驱肠虫药，对治疗钩虫感染、杀灭十二指肠钩虫和美洲钩虫有效。但会发生头晕、头痛、恶心、困倦和酩酊样等副作用。一般用其胶丸空腹时吞服，服药期间忌油、酒，以免中毒。对肝脏和中枢神经系统的毒性较大，对消化道也有较强刺激性，并可引起贫血，故现已少用。
  • 工业制备四氯乙烯方法:工业上大多采用氧氯化法[1，2]或C1～C3烃类氯化法制备四氯乙烯，前者以二氯乙烷为原料，经下述反应制得： 后者是用甲烷、乙烷、丙烷等为原料，在550～700℃时氯化热解制得。 1，以四氯乙烷为原料，高温氯化或在铜、锌催化剂作用下氧化脱氢。 2，以甲烷、乙烷或丙烷为原料，氯化、脱氢，可制得四氯乙烯。 3，以乙炔为原料，与氯反应，生成三氯乙烯，进一步氯化，生成五氯乙烷，再用碱脱氯化氢，可制得[1]四氯乙烯。 4，以乙烯为原料，与氯反应，生成二氯乙烷，二氯乙烷再经氯氧化反应，生成四氯乙烯及副产品三氯乙烯。 参考资料：安家驹 主编;包文滁,王伯英,李顺平 合编.实用
