Restrict 危险品

其他信息

蒸气压:0.03 mm Hg ( 25 °C)
灭火剂:水、泡沫、二氧化碳、干粉
用途一:合成医药、杀虫剂、香料、染料、橡胶防老剂
方法三:1.由煤焦油分离，高温煤焦油中萘约占8%-12%，将煤焦油蒸馏，切取煤油，经脱酚，脱喹啉，蒸馏得成品萘。每吨萘消耗10t煤焦油。2.由石油烃制得：催化重质重整油，催化裂化轻循环油，裂解制乙烯的副产焦油等。其组成如下：项目　　　　　　催化重整油　催化裂化轻循环油　蒸汽裂解副产品　煤焦油芳烃总量（m），% 90-95 45-65 70-95 95-100芳烃组成（m），% 烷基苯类　　　　20 25 20 5　二氢茚和四氢萘　15　　　　　25　　　　　　　　10　　　　　　　5　烷基茚　　　　　2　　　　　 7 18 3 烷基萘类　　　　55　　　　　35　　　　　　　　45　　　　　　　75　联苯和烷基类　　6　　　　　 6 5 10　三环化合物　　　2　　　　　 2 2 2 总计，%　　　　 100　 100 100 100　以上芳烃经催化脱烷基和热解脱烷基均可以生产萘。
用途六:萘是农药生产中的一种原料，可以制造成甲萘酚、乙萘酚，也可以氧化成苯二甲酸酐，进一步生成苯二甲酰亚胺，也可以与氯乙酸生成萘乙酸。可作为杀虫剂亚胺硫磷、甲萘威，除草剂灭草松、敌草胺，植物生长调节剂萘乙酸和萘氧乙酸等的中间体。
外观性质:白色易挥发晶体，有温和芳香气味，粗萘有煤焦油臭味。
稠环芳香烃:萘由两个苯环构成的最简单的稠环芳香烃，俗称“卫生球”。是煤焦油加工的主要产品之一。萘在工业上以粗萘(工业萘和压榨萘)和精萘等产品形式出现。萘的分子式为C10H8，分子量为128.17。熔点为80.28℃，固态密度为1.145g/cm3，液态密度(85℃)为0.9752g/cm3，比热容(100℃)为1809J/(kg·K)，折射率(85℃)为1.5898。萘为无色单斜晶体，易挥发、升华，有特殊气味，易燃，能与空气形成爆炸性混合物;其石油醚溶液在汞灯下呈红紫色荧光，几乎不溶于水，能溶于醚、醇、苯等类溶剂。萘蒸气和粉尘吸入人体内或通过皮肤吸收都能使人中毒，空气中极限允许浓度为20mg/m3。萘是染料、塑料、油漆、医药和农药等工业的基本原料之一，曾直接作为衣物、皮毛防蛀的卫生球使用。萘比苯容易发生取代反应——卤代、硝化、磺化和傅氏反应。α-碳原子上的电子密度较高，生成α-取代产物的速率较快; β-取代产物稳定性较大。取代反应中α-和β-取代产物的比例决定于试剂的性质、催化剂、溶剂、温度等因素。如卤代和硝化反应是不可逆的，一般主要生成α-取代产物，其中溴代反应不需要催化剂就能发生。磺化反应是可逆的，温度较低时，主产物为α-萘磺酸，温度较高时，主产物为β-萘磺酸，当温度升高时，α-萘磺酸可以转变为更稳定的β-萘磺酸：以上信息由Chemicalbook的晓楠编辑整理。

萘熔融-结晶精制:利用熔融的粗萘在冷却结晶时发生组分在液固两相间重新分布的原理，经过多次熔融结晶来提纯萘的工艺过程。是对萘油馏分加工得到的粗萘进行精制的工艺之一。粗萘中的杂质一般会降低萘的熔点，所以当液态粗萘缓慢冷却时萘首先结晶析
