Definitions

  • the catalysts of the present invention may be used unsupported or supported on various conventional carriers such as Si0 2 , AI 2 0 3 , Zr0 2 , Ti0 2 , BP0 4 , SbP0 4 , MgO, montmorillonite, or the like. They may be used in fixed-bed or fluid-bed reactors as desired. When using these catalysts, they are simply substituted for the catalysts previously employed, and the reaction is conducted under substantially the same conditions.
