Preserved Fulltext
The pyrophosphate catalyst K 2 CaP 2 O 7 is a new basic catalyst for Knoevenagel reaction of aldehydes with active methylene in the ethanol at room temperature. The pyrophosphate catalyst bring advantages such as easy separation of the catalyst by simple filtration, possible recycling of the catalyst, use of non-toxic and inexpensive catalysts and especially, elimination of salts and by-product pollutants. In this study, the Knoevenagel reaction between Benzaldehyde and Malononitrile was chosen
