Title:
双極性非プロトン性化合物を含む水性混合物の処理方法
Document Type and Number:
Japanese Patent JP5438974
Kind Code:
B2
Abstract:
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.
