Abstract
The vapour phase Beckmann rearrangement of cyclohexanone oxime to ε-caprolactam is reported over different MEL zeolites viz., silicalite-2, titanium silicate-2 (TS-2), ZSM-11 and alumino-titanium-silicate (Al-TS-2) and fumed silica. TS-2 exhibits 100% conversions with lactam selectivities close to 90%. The titanium containing analogs are also more resistant to deactivation than the parent zeolites. The conversion of cyclohexanone oxime and selectivity for ε-caprolactam increase with temperature. The selectivity for ε-caprolactam increases with the duration of run at all the temperatures.
