Abstract
Procédé de préparation d'une phénylurée substituée dans lequel on fait réagir simultanément une aniline convenablement substituée, de l'urée en excès dans un rapport molaire d'au moins 1,1 par rapport à l'aniline, et une amine secondaire, dans un solvant organique non hydroxylé, à une température de 130 à 250 degrés, avec élimination de l'amoniac au fur et à mesure de sa formation. Les phénylurées obtenues sont utilisées comme herbicides.
