Versuchsvorschrift
To a suspension of 25 g (0.15 mole) 2,3-dichloroaniline in 16 ml H2O, add 39 ml (0.46 mole) concentrated HCl. Stir the mixture at room temperature for about five minutes. Cool the mixture to -5° to 0° C. and add dropwise a solution of 11 g (0.16 mole) NaNO2 in 30 ml H2O. Stir the resulting solution at -5° to 0° C. for about 30 minutes, then filter the solution into an ice-cooled filter flask. Keep the filtrate containing the diazonium salt at about 0° C.
