Beckmann rearrangement of cyclohexanone oxime over modified molecular sieves

摘要

The vapour phase Beckmann rearrangement of cyclohexanone oxime to #epsilon#-Caprolactum over silicoaluminophosphate (MSAPO-5,MSAPO-11) and MZSM-5 has been carried out.The yields of #epsilon#-Caprolactum were 72.0 and 81.5% at 96.0 and 100% conversion over ZnSAPO-11 and TiSAPO-11 molecular sieves,respectively.
