| Abstract: | 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. |
