Process for the treatment of an aqueous mixture comprising a dipolar aprotic compound

摘要

Processes for the treatment of an aqueous mixture comprising a dipolar aprotic compound, comprise: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.
