The pyrolytic decomposition of o-, m-, and p-terphenyls and other potential reactor coolants

Abstract

Experiments were made on the pyrolytic decomposition of o-, m-, and p- terphenyls and mixtures of terphenyls with diphenyl. The effects of competing reactions were also studied by initially adding hydrogen, methane, ethane, propane, and benzene. The results indicate that the disappearance of o-, m-, and p-terphenyl seems to follow formally a first order reaction mechanism. The relative stability of the pure individual components increases in the order: oterphenyl (least stable), p-terphenyl, m-terphenyl (most stable). The activation energy was found to be in the neighborhood of 64 kcal/mole. The activation energy for the diphenyl formation during pyrolysis of an irradiated biphenyl-terphenyl mixture was found to be 47.9 kcal/mole. (P.C.H.)
