Title
(EN) METHOD OF PREPARING DIALKYL LACTAMIDES
(FR) PROCÉDÉ DE PRÉPARATION DE LACTAMIDES DE DIALKYLE
Abstract
(EN)
A method of preparing dialyl lactamides. The method of preparing dialkyl lactamides includes preparing ammonium lactate by reacting at least one compound selected from the group consisting of lactic acid and esters thereof with at least one amine compound, preparing dialkyl lactamides by heat-treating the ammonium lactate, and adding at least one of a polymerization inhibitor and an anti-polymerization agent to a reaction mixture of at least one of the preparing of the ammonium lactate and the preparing of the dialkyl lactamides.
(FR)
Procédé de préparation de lactamides de dialkyle, ledit procédé consistant à préparer un lactate d'ammonium par réaction d'au moins un composé choisi dans le groupe constitué par l'acide lactique et ses esters avec au moins un composé d'amine; à préparer des lactamides de dialkyle par chauffage du lactate d'ammonium, et ajout d'au moins un inhibiteur de polymérisation ou d'un agent anti-polymérisation à un mélange réactionnel constitué au moins de l'une de ladite préparation de lactate d'ammonium ou de ladite préparation de lactamides de dialkyle.
