Abstract

Disclosed is a method for separating butanol. The method uses hydrophobic macroporous polymer adsorbent to separate butanol in a mixed solution, and the process comprises the following steps: 1) using macroporous polymer adsorbent to adsorb butanol in a mixed solution; 2) desorbing butanol from macroporous polymer adsorbent. The method is simple; the separation time is short; the efficiency of butanol recovery is high; and the separating cost is low.
