Obtaining anthracene and carbazole by melt-crystallization

本发明涉及由蒸馏煤焦油所获得的蒽油或其纯化产物制备蒽和咔唑以及后续产物的方法。不加入溶剂，将蒽油或纯化产物粗蒽转变为熔融物。使所述熔融物冷却至咔唑和蒽的结晶点以下。将如此获得的结晶产物从液相中分离出来并蒸馏所获得的结晶产物以获得纯蒽和纯咔唑。 In a method for obtaining anthracene and carbazole and their sequential products from the anthracene oil resulting during coal tar distillation or its purification products, anth...
