R. Hutter et al., SELECTIVE EPOXIDATION OF ALPHA-ISOPHORONE WITH MESOPOROUS TITANIA-SILICA AEROGELS AND TERT-BUTYL HYDROPEROXIDE, Journal of the Chemical Society, Chemical Communications, (24), 1995, pp. 2487-2488
Amorphous, mesoporous TiO2-SiO2 mixed oxides, synthesised using a sol-
gel process followed by extraction with supercritical CO2, show high s
electivities (98%) in the heterogeneous epoxidation of alpha-isophoron
e in ethylbenzene at 60 degrees C.
