Studies on the Oxidation of α-Substituted Styrenes. I. Reactivity and Formation of Reaction Products During the Oxidation of Styrene DerivativesThe liquid phase oxidation of α-tert. -butyl-, α-bromo-, α-chloro-, and α-methyl styrene with pure oxygen was investigated in a closed apparatus in chlorobenzene solution and in presence of cumene and of cumene hydroperoxide in the temperature range 35-125°C. The product yields were determined gaschromatographically.The differences of the activation energies of the epoxide formation and the parallel reactions were calculated. They amount to 27-38 kJ/mol. The epoxide selectivity increases with increasing temperature and decreases with increasing concentration of cumene. Relative chain propagation constants related to the tertiary CH-bond of cumene were determined from cooxidation experiments.
