摘要: The kinetics of the thermal and photochemical oxidation cyclohexane in zeolite Y were investigated using ex situ GC product analysis FTIR solid state NMR spectroscopies. results show that cyclohexyl hydroperoxide, cyclohexanone, cyclohexanol (and water) are formed during BaY. overall percent conversion decreases dramatically at loadings greater than 3 molecules per supercage. Pronounced deuterium kinetic isotope effects observed for both reactions, indicating a proton transfer step is rate-limiting reaction mechanism. For BaY NaY, activation energies 62 (±9) 85 (±3) kJ/mol, respectively, measured.
