Abstract: 
Oxidation of tert-butyl alcohol (TBA) to methacrolein (МA) over Fe-Te-Mo-Ox catalyst (Cat), promoted by Ca(NO3)2 has been investigated. Promoter concentration, which was optimal by the МA yield, has been established (Ca/Mo = 0.05). Using catalyst of such type the MA yield was 87.1 % (calculated for supplied TBA) at the temperature of 663 K, process time of 2.5 s and TBA concentration of 7.0 % with concentration of water vapour in the air of 20 %. Under mentioned conditions TBA conversion was 100 %, isobutylene conversion – 95.5 %, selectivity by MA was 87.6 % and by CO2 – 2.4 %.
