FIELD: chemistry.
SUBSTANCE: in claimed method aluminium oxide is processed in hydrothermal conditions. Hydrothermal processing is carried out at temperature 120-300°C for 0.5-10 h in autoclave after pouring catalyst with water, with weigh ratio aluminium oxide/water 0.5-50, formed product is cooled to room temperature and dried at temperature 110-200°C, after which catalyst calcinations is performed at 550-600°C. Invention also relates to method of obtaining isobutylene by skeletal isomerisation of n-butylenes with application of catalyst, thereof obtained.
EFFECT: increase of content of active centres of skeletal isomeration of n-butylenes.
