METHOD FOR MOLYBDENUM EXTRACTION FROM PRODUCTS OF CATALYTICAL OLEFINE EPOXIDATION WITH ORGANIC PEROXIDES Russian patent published in 2009 - IPC C01G39/00 B01D11/04 B01J23/92 B01J23/28

Abstract RU 2367609 C2

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) T_cr and pressure equal to (1.36-3.4) pressure P_cr whereat T_cr is critical temperature and P_cr 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.
