摘　　要：介绍了以粗蒽为原料,轻苯作溶剂,经溶剂萃取、恒沸蒸馏制取94%的精蒽,再以蒸馏残渣为原料,经升华提取91%的咔唑的试验情况,同时优选出了最佳的工艺参数。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.
