Condensation of cyclohexanone with acetonitrile oil zeolites with different
carcass structures was studied. The highest yield of cyclohexylideneaceton
itrile (80 wt %) at a 98% selectivity of tile process was attained with NaX
zeolite containing 0.5 wt % KOH. Factors responsible for different catalyt
ic activities and selectivities of zeolites are discussed.
