実験手順
30 g of 2,4-dichloro-3-methylbenzoic acid are initially introduced into 83 ml of concentrated H2SO4. 16.7 g of KNO3 are added in portions with ice cooling. The mixture is subsequently warmed at 50° C. for a further 2 hours and then poured onto ice. The nitro compound is isolated and recrystallized from toluene. Melting point 152°-4° C., yield: 24 g.
