PLATINUM OXOACETATE COMPOUNDS FOR PRODUCING HETEROGENEOUS CATALYSTS Russian patent published in 2015 - IPC C07F15/00 B01J23/44 

FIELD: chemistry.

SUBSTANCE: invention relates to production of novel oxoacetate compounds of trivalent platinum M₂Pt₂O(CH₃COO)₅, where M=Li, K, Na, Rb, Cs. Said compounds can be used for synthesis of other platinum compounds, in homogeneous and heterogeneous catalysis as catalyst precursors, and as starting compounds for producing nanosized platinum particles. The platinum compounds are formed either by reacting freshly prepared platinum dioxide tetrahydrate PtO₂*4H₂O with acetates of alkali metals selected from: lithium, sodium, potassium, rubidium, caesium; or by reacting hydroxoplatinates of said alkali metals M₂Pt(OH)₆ with acetic acid in both cases at 90-118°C to form a dark-magenta solution, from which acetic acid is then removed in a vacuum at temperature not higher than 100°C and dark-magenta solid hygroscopic compounds of formula M₂Pt₂O(CH₃COO)₅, where M=Li, Na, K, Rb, Cs, are obtained.

EFFECT: invention enables to obtain stable platinum oxoacetate compounds with high output, which are soluble in water and are suitable for producing heterogeneous platinum catalysts.
