PREPARING TANTALUM-BASED CATALYSTS FOR SELECTIVE OXIDATION OF PROPANE INTO ACRYLIC ACID

摘要

The invention concerns the selective oxidation of propane into acrylic acid with tantalum-based catalysts of formula (I): M?iVaXbTacSidOx, wherein X is the Te or Sb atom. More particularly, the invention concerns the preparation of said catalysts from concentrated solutions and their use for preparing acrylic acid from propane.
