Abstract

L'invention concerne un procédé de production de N'-méthyl-acéthydrazide. Selon l'invention, on fait réagir de l'acéthydrazide, une source de formaldéhyde et de l'hydrogène dans un solvant et en présence d'un catalyseur au palladium, le solvant étant choisi dans le groupe consistant en eau, alcools aliphatiques inférieurs et leurs mélanges, et à une température de 20 à 150 degrés C. L'invention s'applique notamment à la fabrication de méthylydrazine.
