二甲苯 制备方法及用途

制备方法

1.由炼焦副产回收二甲苯二甲苯是生产苯的联产品。根据粗苯各组分的沸点不同,用精馏的方法提取沸程135~145℃的馏分,得二甲苯。具体工艺参见苯。 2.由铂重整油分离回收二甲苯炼油厂常用塔顶油经催化重整,抽提分离,先后可得苯、甲苯、混合二甲苯。如进一步分离可先得邻苯二甲酸、再得间、对混合二甲苯。具体工艺参见苯。 3.甲苯歧化法此法是在催化剂作用下,使一个甲苯的甲基转移到另一个甲苯上,生成苯和二甲苯。反应是用DF-166催化剂(缺铝氢型丝光沸石),以重整甲苯(硝化级)和重整循环氢(85%~90%)为原料,反应温度400℃±2℃,压力为2MPa左右,液体空速为0.5h-1,氢气与油的摩尔比为10∶1的条件下,反应所得的苯和二甲苯的单程收率达45%(质量)以上。液体产物中芳烃组成为:苯22%左右,甲苯44%左右。此法对满足合成涤纶所需对二甲苯具有很重要的意义。 4.将石油轻馏分混合苯经加氢精制,催化重整,分离而得二甲苯。或将焦化粗苯经洗涤、分馏而得。 5.制法 在连续搅拌下将93%以上的工业硫酸慢慢加到工业二甲苯中至硫酸试验合格,静置半小时,取上层二甲苯清液,依次用蒸馏水、15%~20%的氢氧化钠充分洗涤至硫化物含量合格,用无水氯化钙脱水干燥后,进行减压蒸馏,收集合格馏分即为成品。 6. 烟草:FC,40。

沸点:
137-140 °C(lit.)

存储条件/存储方法:
包装完整、轻装轻卸,库房通风、远离明火、高温、与氧化剂分开存放
稳定性相关:

1.如果遵照规格使用和储存则不会分解,未有已知危险反应,避免氧化物。

2.无色透明液体品,具有中等毒性,操作人员应穿戴防护用具。

3.本品具有中等毒性。经皮肤吸收后,对健康的影响远比苯小。空气中二甲苯含量达到0.71×10-6,就能感到臭味,甲苯为0.48×10-6,苯为1.5×10-6。在这样浓度下,苯有引起慢性中毒的危险,而对二甲苯几乎不用担心。高浓度二甲苯蒸气,例如:1000×10-6以上,除了伤害黏膜,刺激呼吸道外,还呈现兴奋,麻醉作用,甚至造成出血性肺气肿而致死。二甲苯经口服引起中毒的情况极少。若不慎口服了二甲苯或含有二甲苯的溶剂时,即强烈刺激食道和胃,并引起呕吐,还可能引起出血性肺炎,应立即饮入液体石蜡,延医诊治。二甲苯蒸气对小鼠的LC为6000×10-6,大鼠经口最低致死量4000mg/kg。 

4.是邻二甲苯、间二甲苯、对二甲苯的混合物,称混合二甲苯,以间二甲苯的含量较多。
