CATALYST FOR SYNTHESIS OF BETA-PICOLINE BY CONDENSATION OF ACROLEINE WITH AMMONIA AND METHOD OF PREPARATION THEREOF Russian patent published in 1997 - IPC

Abstract RU 2079360 C1

FIELD: catalysts for organic syntheses. SUBSTANCE: proposed catalyst can be used in synthesis of β-picoline which is starting material for preparing a series of drugs (e.g. nicotinic acid), pesticides, and other biologically active substances. Catalyst constitutes alumino-silicon composition containing 19-50 mol % silica and 50-81 mol % alumina and is prepared either by precipitating components, or by mixing silicon- and aluminum-containing substances followed by shaping, drying, and calcination at 700-1000 C. EFFECT: increased picoline yield (70% against 54%) and productivity in respect to picoline. 4 cl
