dc.description.abstractThe isomerisation of α-pinene oxide to campholenic aldehyde was investigated over a number of solid acids - B2O3/SiO 2, ZnCl2/MCM-41, Al-MCM-41, HY zeolites and Al-MSU-S FAU. Irrespective of the loading, the selectivity to campholenic aldehyde over B2O3/SiO2 was ∼69% at 25°C. The initial rate for the isomerisation of α-pinene oxide was a maximum at 15wt.% B2O3 loading. Both Lewis and Brønsted acid sites were present in B2O3/SiO 2 samples although at higher loadings of B2O3, Brønsted acidity predominated. Under anhydrous conditions, no crystalline phases of boron oxide were detected up to a B2O 3 loading of 20wt.%, but upon exposure to ambient environment, boric acid was formed. The Lewis acid, ZnCl2/MCM-41, was not very active but highly selective (85%) for campholenic aldehyde. Al-MCM-41 and HY zeolites showed high conversion but the selectivity was dependent on the Al content, varying from 49 to 66%. By incorporating both microporosity and mesoporosity in mesostructured Al-MSU-SFAU (Si/Al 70), good activity and selectivity to campholenic aldehyde, 86%, was observed. © 2004 Elsevier B.V.
