Most of the technical anthracene produced in the coking industry is used for anthraquinone product. The 1973 output was 782 tons of technical anthracene with about 93.0-93.5 percent of the nominal substance. The demand for anthracene is now over 2000 tons and it will double or triple very soon. The performance of the anthraquinone producers and the quality of their product are largely determined by the quality of the original anthracene. Its purity is the basic criterion, and it should be at least 96 percent by weight. The availability of anthracene in coal tar is quite substantial; even at the present coke output level, it greatly exceeds the foreseeable demand. However, the coking plants are unable at present to refine anthracene beyond the 93.5 percent level. The method of making refined anthracene carried out at the Avdeevka Coke and Chemical Works consists of a three-stage counterflow acetone treatment of the crude coking-plant anthracene at 50/sup 0/C. The possibility of substituting recrystallization for the final (third) washing stage of the process as carried out at the Avdeevka plant has now been investigated. The recrystallized product resulting from the described process was 96 to 97 percent anthracene.
