Abstract

Solvent selection is the key of solvent crystallization method In this paper, the optimal crystallization conditions for xylene and DMF extraction of refined carbazole is studied that the crude carbazole as a raw material, dissolved temperature is 85 , crystal-keeping time is 90min, the solvent ratio is 1.8g/ml, the cooling crystallization time is 50min,the cooling crystallization temperature is 25 . The results showed that the process has hardly environmental pollution and the lower cost the solvent was circularly utilized the Purity of refined anthracene and carbazole could reach to more than 96% the total yield of refined anthracene could reach over 67%.
