Zusammenfassung: | 1,229,763. Anthracene. R TGERSWERKE A.G. 27 Jan., 1970 [12 Feb., 1969], No. 3796/70. Heading C5E. The anthracene content of an aromatic fraction containing anthracene, phenanthracene and homologues thereof (e.g. methylanthracene and methylphenanthracene) is increased by subjecting the fraction to hydrodealkylation (with accompanying isomerization) at 700-850 C. for 1-10 sees. in the presence of a 10-20 molar excess of hydrogen. Crude anthracene can be recovered by distillation. |
