FIELD: chemistry.

SUBSTANCE: invention relates to the catalyst for synthesising the 2- and 4-picolines, method for its producing and the method for producing the 2- and 4-picolines. The catalyst which can be used in synthesis of 2- and 4-picolines containing the heteropolyacid from the group containing the silicon tungsten acid, phosphorus tungsten acid and the vanadium tungsten acid applied upon the silica gel substrate with the particles size of 6-14 mesh, is described. The method for producing the catalyst is also described, which includes the dissolution of heteropolyacid in distilled water, stirring the obtained mixture with the needed amount of the silica gel to obtain the suspension; mixing the suspension till even impregnation, air drying the suspension at 200-250°C up to 1.5 hour; following heating the suspension at 300 to 400°C within 0.5 to 1.5 hours and cooling the obtained product till the room temperature in the exiccator to obtain the needed catalyst. The method for producing the of 2- and 4-picolines is described which includes the interaction of acetaldehyde and ammonium hydrate at heating in presence of the said catalyst.

EFFECT: stable highly selective and active catalyst is available.
