THE DECOMPOSITION OF CUMENE HYDROPEROXIDE BY METAL SALTS AND COMPLEXES IN STYRENE SOLUTION
The rate of decomposition of cumene hydroperoxide in styrene at 30 °C. is increased considerably by the presence of various metal salts and complexes. The rate increases in the presence of certain metal salts and complexes whether the metal is oxidizable, reducible, or incapable of undergoing a valence change. Both the metal and the nonmetal portion appear to influence the rate. The molar ratio of cumene hydroperoxide decomposed to metal complex added may be well over 1000. Most of the decomposition of cumene hydroperoxide in the presence of ferric phthalocyanine does not produce free radicals capable of initiating the polymerization of styrene and may proceed by an ionic chain mechanism.
