Abstract
The condensation of barbituric acid with aldehydes under microwave irradiation in dry media has been investigated in the presence of NH4OAc/AcOH (4/3, w/w) (41–54%), Montmorillonite K-10 (49–60%), Silica gel (52–63%), basic Al2O3 (56–67%), NaCl (57–69%), Montmorillonite KSF (62–70%), and KSF + NaCl (1:1, w/w) (70–89%).
