observed. Furthermore, isopropylamine was formed on silicalite-1 by the reaction of isobutane and byproducts of the Beckmann rearrangement, such as hydroxylamine. In contrast, no influence and conversion of methanol were found during the Beckmann rearrangement of 15N-cyclohexanone oxime on the mesoporous SBA-15 and [Al]SBA-15 materials.
