Abstract: Oxidation of tert-butyl alcohol (TBA) to methacrolein (IA) over Fe-Te-Mo-Oх catalyst (Cat),promoted by Ca(NO3)2 has been investigated. Promoter concentration, which was optimum by the IA yield, has been established (Ca/Mo = 0.05). Using catalyst of such a 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 the 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 12.4 %. Досліджено процес окиснення третбутилового спирту (ТБС) до метакролеїну (МА) на Fe-Te-Mo-Oх каталізаторі (Кт), промотованому Ca(NO3)2. Встановлено оптимальну за виходом МА концентрацію промотора (Ca/Mo = 0.05). На каталізаторі такого типу вихід МА на поданий ТБС при Т= 663К, 2,5 с становить 87,1% при концентрації ТБС 7.0% у повітрі з 20% пари води. За цих умов конверсія ТБС 100%, ізобутилену - 95,5%, селективність за МА - 87,6%, за СО2 - 12,4%.
