WebThe process involves dissolving a solid into solution, then allowing the dissolved substance to gradually crystallize. This produces compounds high in purity, a quality which can be seen by the presence of uniform crystals. Recrystallization is … WebFeb 5, 2016 · The crystal structures of three nitrogen-rich salts were determined. Thermoanalysis of the cationic azide and triazene showed exothermal decomposition. The triazene exhibited negative solvatochromism in polar solvents involving the dipolarity π* and hydrogen-bond donor acidity α of the solvent. 5-Azido-4-(dimethylamino)-1-methyl-1,2,4 ...
