Selective epoxidation of α-isophorone with mesoporous titania–silica aerogels and tert-butyl hydroperoxide
Abstract
Amorphous, mesoporous TiO2–SiO2 mixed oxides, synthesised using a sol–gel process followed by extraction with supercritical CO2, show high selectivities (98%) in the heterogeneous epoxidation of α-isophorone in ethylbenzene at 60 °C.
