Abstract: In a continuous process for preparing amides by reaction of esters with primary or secondary amines, the reactants are introduced into a column in which there is, both above and below the point of introduction, a countercurrent flow of ascending vaporous products and descending liquid products (the amide being withdrawn from a point below the supply point), and a temperature gradient increasing from top to bottom. The esters are derived from C1- 4 acids and C1- 4 alcohols and the amines have 1-12 C atoms and may contain 1 or 2 OH groups or ether bridges; the column temperatures are not more than 260 DEG C. at the bottom and at least 20 DEG C. at the top. A part only of the top product is removed at a minimum reflux ratio of 2: 1. Exemplified products are HCONMe2, HCONHEt, HCONEt2, HCONBu2, HCONH (cyclohexyl) and AcNHEt.
