FIELD: industrial organic synthesis.
SUBSTANCE: molybdenum is recovered from catalytic olefin epoxidation products using organic hydroperoxides. Method comprises treating heavy epoxidate fraction with alkali solution, treating resultant spent alkali stream with extractant, and subsequent precipitation of molybdenum trisulfide using sulfur-alkali effluents formed in production of olefins by pyrolysis of hydrocarbon feedstock.
EFFECT: increased molybdenum recovery degree and simplified operation.
