4-Chloroaniline → Monuron

関与物質

反応手順

A mixture of 12.8 g (0.1 mole) of 4-chloroaniline, 10.3 g (0.1 mole) of methyl N,N-dimethyl-carbamate, 20 ml of dimethyl-hexadecylamine and 100 ml of high boiling petroleum fractions (bp.: 160°-180° C.) is reacted as described in Example 12. When the reaction has proceeded to about 90%, as indicated by the chromatogram, the reaction is terminated. A solution of N-(4-chlorophenyl)-N',N'-dimethyl-urea (monuron) is obtained, which can be applied directly in the preparation of herbicidal compositions, such as spray liquids or impregnated granules.
