Abstract

The oxidation of α-terpinene by molecular oxygen is shown to occur by a radical chain mechanism involving hydroperoxy radicals. The principal molecular reaction products are H2O2 and 1-methyl-4-isopropylbenzene. The rate constants for chain propagation and chain breaking measured at 35–70°C are (liter/mol·s) lgk3 = 7.10− (6700±400)/4.57T and lgk5 = 9.80− (2700±300)/4.57T respectively.
