FIELD: industrial organic synthesis and catalysts.
SUBSTANCE: invention provides alternative bimetallic catalyst composition comprising a cobalt component and a iron component alloyed with ligand selected from group consisting of T-heterocycle residue, phosphine, and porphyrin. 1,3-Butanediol production process comprises providing reaction mixture containing ethylene oxide, carbon monoxide, hydrogen (H2/CO molar ratio being between 2:1 and 6:1), inert solvent, and above-defined catalyst composition, and heating this reaction mixture to temperature from 30 to 150°C at pressure from 1500 to 2500 psig (1034 to 17420 kPa) to form biphasic mixture of reaction products composed of (i) upper phase including at least wt 50% of solvent, at least 50 wt % of catalyst composition plus unreacted ethylene oxide and (ii) lower phase containing more than 50% of 1,3-butanediol.
EFFECT: achieved single-stage production of 1,3-butanediol with minimum amounts of impurities and by-products, and increased stability of catalyst.
