Abstract:

A new technology of refined anthracene preparation by emulsion crystallization method is studied in laboratory where the factors affecting the quality of refined anthracene,such as amount of emulsifier,ratio of water to solvent (w/w) and amounts of additives,etc. have been investigated.The result shows that the purity of pure anthracene can reach above 95% and meet national specification Gr.I after primary emulsification when a compound emulsifier (SDBS+Span20) is adopted and acetophenone is used as solvent.
