✦ Synopsis

Novel basic catalysts with high specific surface areas have been synthesized by activation under ammonia of an aluminophosphate oxide precursor. The nitrogen content as well as the acid-base *properties depend on both time and temperature of nitridation. The conversion and reaction rate in Knoevenagel condensation are related to the nitrogen content.
