Versuchsvorschrift
It is known, from J. pract. Chem. [2] 110 (1925) 300, to react 2,4-dinitrochlorobenzene with a large excess of cyanamide in aqueous ethanol to give 2,4-dinitrophenylcyanamide and to precipitate the latter by means of hydrochloric acid. When this precipitate is heated together with alcoholic hydrochloric acid, 2,4-dinitrophenylurea is obtained therefrom.
