Web2 Jul 2009 · The electronic structure, absorption spectra, and thermodynamic properties of crystalline styphnic acid and its metal salts (potassium, barium, and lead styphnates) have been studied using density functional theory within the local density approximation. The results show that the metal states affect the electronic structure of styphnic acid by … WebThe synthesis of picric acid was achieved by nitration of 2,4-dinitrophenol using concentrated H2SO4 and HNO3. The nitration of m-cresol using sulfuric acid and nitric acid resulted in vigorous reaction and hence, we attempted nitration using potassium nitrate and sulfuric acid to give 2,4,6-trinitro-m- cresol with excellent yield (Scheme 1). petco buen fin 2022
