| description | L'invention concerne un procédé de préparation d'un dérivé de l'acétamide ainsi que le dérivé obtenu par ce procédé. Suivant le procédé de l'invention, on obtient le di-n-propylacétamide de formule :
Process for preparing di-n-propyl acetamide of the formula: whereby di-n-propyl acetonitrile is hydrolyzed by means of 80% sulphuric acid aqueous solution in the proportion of 2 to 2.5 g of dilute acid/g of nitrile, at a temperature between 80 DEG C and 130 DEG C to obtain the desired amide. |
