Abstract
"Process for preparing herbicidal products derived from urea", mainly benzoylurea, characterized in that it is prepared by the condensation of an amine with an isocyanate-phenyl to form a substituted phenylurea, and the subsequent reaction of this phenylurea with a benzoyl chloride , whose nucleus can optionally be substituted, said reaction being carried out in the presence of an acceptor of hydrochloric acid constituted by a nitrogenous base.
