-甲基萘从洗油中分离提纯的研究 -

介绍了一种从含2-甲基萘量较低的洗油中分离、提纯2-甲基萘的有效方法。所得2-甲基萘经气相色谱分析其纯度可达99.5%,回收率在79.8%以上,此方法具有工艺简单、产物纯度高、污染低、共沸剂可以重复利用和成本低等特点。 Introduce an effective method about the separation and purification of low level 2-Methylnaphthalene from wash oil.The determination of gas chromatography shows that the purity of 2-methyl naphthalene reach 99.5%, and the recovery rate reach 79.8% or more.The process has many characteristics such as simple process,higher purity,low pollution,recycle use of azeotrope former,lower lost and so on
