METHOD OF EXTRACTING MOLYBDENUM FROM PRODUCTS OF CATALYTIC EPOXIDATION OF OLEFINS Russian patent published in 2012 - IPC C01G39/00 C07D301/19 B01J38/68

Abstract RU 2453498 C1

FIELD: chemistry.

SUBSTANCE: method involves treating a heavy epoxidate fraction with alkali solution and treating the formed spent alkali stream with an extractant, followed by deposition of molybdenum trisulphide. At the extraction step, a washing solvent is added to the alkali stream, said washing solvent being C₅-C₈ alcohols, aldehydes, ketones or mixtures thereof.

EFFECT: method enables to obtain solutions with higher molybdenum concentration, increases degree of molybdenum extraction, reduces contamination of process effluents, which then improves quality of the molybdenum trisulphide precipitate and simplifies the waste treatment process.
