To separate polycyclic aromatic hydrocarbons from coal tar, which have very high melting point and difficult to purify, the pressure induced crystallization method was modified to use solvent and it was applied to the separation of anthracene from model mixture and real anthracene cake. At the condition of 333K, 150MPa, high purity anthracene crystal with 99.1 wt% was recovered from the model mixture by this method. The purification of real anthracene cake was also achieved by this method, however, the purity of recovered anthracene crystal was slightly influenced by the minor compounds in real anthracene cake.
