| Abstract: | A test is described. In the test the refined anthracene with the purity of 94% is extracted through solvent extraction and constant boiling distillation by taking crude anthracene as raw material and light benzol as solvent, and then by taking distilled residual sludge as raw material the refined carbazole with the purity of 91% is extracted via sublimation. At the same time the optimum process parameters are selected. |
