Studies on Synthesis of 5-Arylidene Barbituric Acid

Synthesis of 5-Arylidene Barbituric Acid and effections of factors such as solvent,temperature,catalyst were carried out by Knoevenagel condensation reaction of aromatic aldehyde and barbituric acid.It showed that water as solvent could improve product yield and KF/Al2O3 was consided as a catalyst having well effiecient.98% product yield could be get
