Summary:The catalytic effect of barium ferrite magnetic particles on aldol condensation was studied from the viewpoint of the reduction of this effect. The poisoning caused by different kinds of oxoacid ions was examined, and tungstate and molybdate ions were found to show high effectiveness for the deactivation of the above catalysis. These ions were adsorbed selectively on the side-planes (1100) of the hexagonal particles, where the catalytic activity was found to be about 15 times higher than that of the C-planes (0001).
