METHOD FOR THE PREPARATION OF ANTIMONATE CATALYSTS FOR (AM) OXIDATION OF ALKANES AND ALKENES

摘要

The method is applied for the preparation of the catalyst VaSbbMmNnOx used in the amoxidation of C2-C5 hydrocarbons to the respective unsaturated nitrile. By the method aqueous mixture containing V205 and Sb203 is heated to temperature range from 100 to 250 degrees C, preferably from 110 to 175 degrees C and most preferred it should be from 120 to 160 degrees C at autogenous pressure with agitation until the formation of a catalyst precursor. The precursor is dried and calcinated until the formation of the end catalyst. 19 claims
