Versuchsvorschrift

To stirred fuming nitric acid (200 ml) at 0° C. was added slowly 2,4-dichlorotoluene (50 g, 0.3mole). Upon completion of addition, the reaction mixture was stirred for one hour, then was poured into water (100 ml). A yellow precipitate was collected by filtration to yield 62.0 g of 2,4-dichloro-5-nitrotoluene, m.p. 40°-44° C.
