The formation of aromatic hydrocarbons at high temperatures. XXII. The pyrolysis of phenanthrene

Abstract

The pyrolysis of phenanthrene at 700° and at 850° has given tars in which 7 and 13 aromatic compounds have been identified respectively. Mechanisms for the formation of these compounds are discussed, with special reference to the formation of anthracene by rearrangement of the intermediate tetrahydrophenanthrene.
