Characterization of the combustion products of polyethylene

Polyethylene (PE) was burned in a tube-type furnace with an air flow at a temperature of 600~900°C. Combustion products were collected with glass wool, glass fiber filter, and XAD-2 adsorbent. The analysis of the products was performed with GC-FID and GC-MSD. At low temperature, hydrocarbons were the major components, while at higher temperature the products were composed of polycyclic aromatic hydrocarbons. With the high performance of the Hewlett-Packard 6890GC-5973MSD, more compounds were identified in comparison with previous studies.

Photoisomerization and Photocyclization Reactions of 1-Styrylanthracene

On triplet sensitization, 1-styrylanthracene (1SA) undergoes adiabatic cis->trans one-way isomerization (3c*->3t*) similarly to 2-anthrylethylenes.However, upon direct irradiation, cis-1SA in the singlet excited state mostly undergoes cyclization to a dihydrophenanthrene-type product (DHP), 4a,4b-dihydrobenzochrysene, competing with an inefficient intersystem crossing to 3c* followed by one-way isomerization.The produced DHP, in deaerated benzene, is reverted to cis-1SA by a thermal (Ea = 14.9 kcal mol-1) or a photochemical pathway; however, under an oxygenated atmosphere DHP gives benzochrysene.A failure in the production of a cyclized product upon the excitation of trans-1SA shows that the isomerization really takes place in a one-way fashion.
