Abstract
The now-vacuum pyrolyses of 5H-dibenzo[a,d]cyclohepten-5-one (5); 10,1 1-dihydro-5H-dibenzo[a,d]cyclohepten-5-one (6) and 5,7-dihydro-6H-dibe nzo[a,c]cycloheptena-6-one (7) were examined at 1.033 mbar and differe nt temperatures between 850 degrees C and 1050 degrees C. The formatio n and the time dependence of reaction products (phenanthrene from 5; a nthracene, phenanthrene, fluorene, dihydrophenanthrene from 6; phenant hrene, dihydrophenanthrene and fluorene from 7) as function of tempera ture are discussed. The suggested reaction mechanisms am compared with related literature data.
