Abstract
Abstract A catalyst suitable for the production of Acrylonitrile from propylene or acrolein, Acrylic acid from propylene or acrolein, and Acrolein from propylene Comprising silver oxide and molybdenum oxide in a molar ratio of from about 0.1 to about 2.0. The catalytic reactions using this new catalyst are directed towards the desired end product by variation of the molar ratio of silver oxide to molybdenum oxide.
