V. Indira et al., Kinetics and mechanism of styrene oxidation using transition metal substituted dodecatungstophosphate, REACT KIN C, 73(1), 2001, pp. 99-107
Tetraalkylammonium (TAA) salts of transition metal substituted dodecatungst
ophosphate, (TAA)(5)PW11O39.H2O (where TAA = (C2H5}(4)N (TEA) (C3H7}(4)N (T
PA), and (C4H9}(4)N (TBA), and M = Mn2+, Fe2+ and Co2+) catalyzed the oxida
tion of styrene with H2O2 at 353 K. Except for the Mn2+ salt, other TAA sal
ts were found to be active and gave mainly benzaldehyde and styrene oxide p
roducts. Among the catalyst tested, TBA (tetrabutylanunonium) salt of Co2was more active in styrene oxidation. Kinetics of TBA-PW11CoO39 catalyzed o
xidation of styrene have been investigated and mehanism for oxidation of st
yrene has been proposed.
