Zusammenfassung:	FIELD: chemistry. ^ SUBSTANCE: product of olefins epoxidation by organic peroxides are fractionated, the molybdenum-containing heavy fraction is washed from the oxidation by-products with caustic soda solution. The ligand is added to the obtained worked out alkali solution in order to bind the dissolved molybdenum to metal-organic complex with following mixture treatment with extragent at temperature equal to (1-1.18) Tcr and pressure equal to (1.36-3.4) pressure Pcr whereat Tcr is critical temperature and Pcr is critical pressure of the extragent. The molybdenum-containing compounds are precipitated from extract. ^ EFFECT: increased degree of molybdenum extraction (45,38% - 98,36%) from the worked out alkali solution independently of its composition. ^ 1 dwg, 2 tbl, 6 ex Изобретение относится к области нефтехимии. Продукты реакции эпоксидирования олефинов органическими гидропероксидами разделяют на фракции. Содержащую молибден тяжелую фракцию эпоксидата промывают от побочных продуктов окисления раствором каустической соды. В образовавшийся отработанный щелочной поток добавляют лиганд для связывания присутствующего в нем молибдена в металлорганический комплекс и обрабатывают экстрагентом при температуре (1-1,18)Ткр и давлении (1,36-3,4)Ркр, где Ткр - критическая температура, а Ркр - критическое давление используемого экстрагента. Молибденсодержащие соединения осаждают из экстракта. Изобретение позволяет обеспечить степень извлечения молибдена от 45,38% до 98,36% из отработанного щелочного потока независимо от его состава. 1 ил., 2 табл.
