Title (EN) PROCESS FOR THE TREATMENT OF AN AQUEOUS MIXTURE COMPRISING A DIPOLAR APROTIC COMPOUND
(FR) PROCÉDÉ DE TRAITEMENT D'UN MÉLANGE AQUEUX COMPRENANT UN COMPOSÉ APROTIQUE DIPOLAIRE
Abstract: front page image
(EN)The invention relates to a process for the treatment of an aqueous mixture comprising a dipolar aprotic compound, comprising: a) an adsorption step, in which the aqueous mixture is brought into contact with a porous adsorbent, whereby the porous adsorbent is chosen such that the dipolar aprotic compound adsorbs to it more readily than water; b) a desorption step, in which the porous adsorbent is brought into contact with a desorbing agent, whereby a recovery solution is formed comprising the desorbing agent and the dipolar aprotic compound.
(FR)L'invention concerne un procédé de traitement d'un mélange aqueux comprenant un composé aprotique dipolaire, comprenant : a) une étape d'adsorption, lors de laquelle le mélange aqueux est mis en contact avec un adsorbant poreux, l'adsorbant poreux étant choisi de manière à ce que le composé aprotique dipolaire s'adsorbe plus facilement sur lui que l'eau; b) une étape de désorption, lors de laquelle l'adsorbant poreux est mis en contact avec un agent désorbant. On obtient ainsi une solution de recouvrement qui contient l'agent désorbant et le composé aprotique dipolaire.
