Beschreibung
Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: method involves treatment of heavy olefin fraction by an alkali solution, processing of obtained discharge alkali flow by extragent, and further precipitation of molybdenum trisulfide by precipitator. According to invention, sodium hydrosulfide is applied as molybdenum trisulfide precipitator. The method allows regulation of molybdenum trisulfide precipitator feed, reduction of precipitation reactor dimensions and energy consumption of heating and stirring, significant reduction waste and hydrogen sulfide discharge at high molybdenum extraction degree of 90.5-97.6%. ^ EFFECT: improved method of molybdenum extraction from products of catalytic olefin epoxidation by organic hydroperoxides. ^ 6 ex
