Modified desilicated natural zeolite as catalyst for Knoevenagel reaction

Natural zeolite (NaZ) has wide range of usage in agriculture and waste water treatment. However, its application as catalyst has not been widely studied. In this research, natural zeolite was modified its property and applied as base catalyst in the Knoevenagel reaction. The modification was done by...
