Abstract

Acenaphthylene is obtained by passing vapours of acenaphthene at temperatures of 500--850 DEG C. and at reduced or atmospheric pressure over a solid dehydrogenation catalyst comprising carbon or silicon or a non-reducible heavy metal compound. The acenaphthene may be diluted with an inert gas. Specified catalysts are crystalline silicon, lustrous carbon, oxides and sulphides of zinc, chromium, molybdenum, tungsten, uranium, and manganese, and salts in which these oxides and sulphides are the acidic component or the basic component is an alkaline earth metal, a rare earth metal, titanium, zirconium, hafnium, thorium, zinc, or aluminium. The catalysts may in addition contain other alkaline earth metal or alkali metal compounds. They may be mounted on carriers and may be treated with hydrogen-containing gases before use.
