FIELD: chemistry.
SUBSTANCE: improved is method of continuous propane epoxidation with hydrogen peroxide in presence of titanium-silicalitic catalyst and methanol solvent, in which catalyst is periodically regenerated by washing with methanol at temperature not less than 100°C, reaction of epoxidation between two regeneration stages is carried out during time intervals constituting more than 300 h.
EFFECT: use of regenerated catalyst during long period of time ensuring constant conversion and selectivity on product in process of epoxidation.
