  • 爆炸物危险特性:与空气混合可爆炸
  • 无色澄清易流动的液体。系邻、间、对三种同分异构体的混合物。有特殊气味。能燃烧。能与无水乙醇、醚和氯仿混合,几乎不溶于水。易燃,蒸气能与空气形成爆炸性混合物,爆炸极限约为1%-7%(积)。低毒,半数致死浓度(大鼠,吸入)0.67%/4h。有刺激性。蒸气高浓度时有麻醉性。
  • 用途四:溶剂、测定许多有机化合物中水分,显微镜清洁剂。硅元件和热敏电阻等的清洗剂。混合二甲苯是邻;间;对二甲苯和乙基苯的混合物。作为化学原料使用时,可将各异构体预先分离。混合物主要用作油漆涂料的溶剂和航空汽油添加剂。
  • MOL 文件:1330-20-7.mol
  • 残留与蓄积:在职业性接触中,二甲苯主要经呼吸道进入身体。对全部二甲苯的异构体而言,由肺吸收其蒸气的情况相同,总量达60%~70%,在整个的接触 时期中,这个吸收量比较恒定。二甲苯溶液可经完整皮肤以平均吸收率为2.25µg/(cm3·min)(范围0.7~4.3µg/(cm3·min))被吸 收,二甲苯蒸气的经皮吸收与直接接触液体相比是微不足道的。二甲苯的残留和蓄积并不严重,上面我们已经说过进入人体的二甲苯,可以在 人体的NADP(转酶II)和NAD(转酶I)存在下生成甲基苯甲酸,然后与甘氨酸结合形成甲基马尿酸在18小时内几乎全部排出体外。即使是吸入后残 留在肺部的3%-6%的二甲苯,也在接触后的3小时内(半衰期为0.5~1小时)全部被呼出体外。评价接触二甲苯的残留试验,主要是测定尿内甲基 马尿酸的含量,也有人建议测
  • 用途三:混合二甲苯是邻、间、对二甲苯和乙基苯的混合物。作为化学原料使用时,可将各异构体预先分离。混合物主要用作油漆涂料的溶剂和航空汽油添加剂。
  • 方法一:1.炼焦副产回收苯高温炼焦副产的高温焦油中,含有一部分苯。首先经初馏塔初馏,塔顶得轻苯,塔底得重苯(重苯用作制取古马隆树脂的原料)。轻苯先经初馏塔分离,塔底混合馏分经酸碱洗涤除去杂质,然后进吹苯塔蒸吹,再经精馏塔精馏得纯苯。2.铂重整法用常压蒸馏得到的轻汽油(初馏点约138℃),截取大于65℃馏分,先经含钼催化剂,催化加氢脱出有害杂质,再经铂催化剂进行重整,用二乙二醇醚溶剂萃取,然后再逐塔精馏,得到苯、甲苯、二甲苯等产物。
  • 毒性以及对人体健康的危害:二甲苯具有中等毒性。经皮肤吸收后,对健康的影响远比苯小。若不慎口服了二甲苯或含有二甲苯溶剂时,即强烈刺激食道和胃,并引起呕吐 ,还可能引起血性肺炎,应立即饮入液体石蜡,延医诊治。二甲苯蒸气对小鼠的LC为6000*
  • 毒性分级:中毒
  • 二甲苯同分异构体:二甲苯是苯环上两个氢原子被两个甲基取代的芳香烃。在焦化工业中,它是粗苯精制产品之一。二甲苯不溶于水,溶于乙醇和乙醚等有机溶剂。二甲苯有三种种同分异构体,即邻二甲苯、间二甲苯和对二甲苯,此外具有与二甲苯相同的元素组成的乙苯也是它的同分异构体。它们的分子式都为C8H10,分子量为106.16,其他物理性质则各不相同。 邻、间、对二甲苯三者化学性相近。侧链烷基可在催化剂作用下氧化,间二甲苯、对二
