7 FOEMULA OF ANTHRACEN. Graebe, and along with him probably all chemists, de- pending on Van Dorp's synthesis, and on the behaviour of anthracen with soda-lime, have adopted this latter structural formula, as belonging to anthracen. It shows that anthra- quinon is not a true quinon, but a double… … We may here go so far as, depending on the formation of phthalic acid, to resolve the formula more in such a direction that in one at le.ast of the benzol nuclei, the lateral chains have the position 1^ 2 ; the formation of ali- zarin from phthalic acid and pyrocatechin makes this very probable.…
