99.5% | With nitric acid; In acetonitrile; | Benzo-15-crown-5 nitration was carried outby nitric acid, 58%, over boiling reaction mass in theacetonitrile media, using relevant method17.Nitric acid of various concentrations can beused in nitration reaction. In some cases, diluted nitric acid (which is poor nitration agent and quite strongoxidizing agent) is also used due to the constantpresence of nitrous acid that hinders nitration.Another drawback of diluted nitric acid, which limitsits use, is its ability to express nitrating effect only athigh temperatures, which are featured by prevailingside oxidation reaction. Concentrated nitric acidshows nitrating effect at lower temperatures and lesslikely to cause undesirable oxidation, which is why wecarried out a nitration of resulted <strong>[14098-44-3]benzo-15-crown-5</strong>with nitric acid, 56%, in the acetonitrile media.
