SORBENT-CATALYST PREPARATION METHOD Russian patent published in 2010 - IPC B01J23/44 B01J21/18 B01J37/02 

FIELD: chemistry.

SUBSTANCE: invention relates to sorption techniques, particularly for preparing sorbent-catalysts used as organic synthesis catalysts when treating vodka in order to convert organic impurities in the vodka to high-molecular weight compounds which give the beverage good taste. The invention describes a method of preparing the sorbent-catalyst, involving saturation of active carbon, having ratio of volume of sorption space to total pore volume equal to 0.45-0.55 with 0.01-0.20 wt % palladium (II) chloride, maturation of the saturated carbon for 6-10 hours, reduction of palladium (II) to palladium metal with a sodium formate solution heated to 80-90°C and taken in ratio carbon: solution equal to 1: (4-5).

EFFECT: method of preparing sorbent-catalysts increases content of acetyl acetate in vodka classifications to 0,67 mg/dm³, which improves quality of the vodka and enables to attain a taste mark of 9,50.
