✦ Synopsis

Abstract

The products of the pyrolysis of light and heavy biphenyl are molecular hydrogen (or deuterium respectively), benzene, terphenyl and quaterphenyl. Several kinetic ways are discussed to explain the activation energy of 66 ± 8 kcal/mole for the decomposition of biphenyl, its isotope effect and the isomeric distribution of the terphenyls (10%, o, 48% m, 42% p) and quaterphenyls (1%oó, 11% om′, 8% op′, 29% mm′, 39% mp′, 9,12% pp′) produced. There are not enough data to allow a clearcut decision of their way of formation.
