摘要

Selective oxidation of cyclohexanone to ɛ-caprolactone by H2O2 was investigated on β- zeolites with various Si/Al ratio. The yield of ɛ-caprolactone was increased with decreasing Si/Al ratio. The β-zeolites in which Si/Al ratio was lower than 117 showed the almost constant yield of ɛ-caprolactone with slight decrease of selectivity. The hydrolysis product, 6- hydroxycaproic acid, was observed. The conversion of H2O2 was also increased with ...
