Acenaphthene (1,2-dihydroacenaphthylene; 1,8-ethylene naphthalene) is a white to slightly yellowish solid that belongs to the polycyclic aromatic hydrocarbons . Acenaphthene is found to 0.3% in coal tar .
Acenaphthene is required for the production of plastics, dyes, insecticides and pharmaceutical products, but mainly for the large-scale production of naphthalic anhydride . Technically, it is obtained by hydrogenating acenaphthylene .
