Vapor-phase Beckmann rearrangement of cyclohexanone oxime over B2O3 catalysts supported on TiO2-ZrO2 mixed oxide
A novel catalyst, boria supported on titania-zirconia mixed oxide, exhibits very high catalytic activity and selectivity in vapor-phase Beckmann rearrangement of cyclohexanone oxime to epsilon-caprolactam. It gives 99.7% oxime conversion and 97.0% lactam selectivity at 300degreesC.
