摘要
介绍了用于分离醇 /水混合物的渗透汽化法、蒸汽渗透法、共沸精馏法、萃取精馏法、超临界萃取和吸附法 ,具体分析了各类方法的特点和应用前景。
This paper introduces six methods to separate low molecular weight alcohols from aqueous solutions,they are pervaporation,vapor permeation,azeotropic distillation,extractive distillation,supercritical extraction and adsorption.Their characteristic and future application in industry are discussed in details.We recommend that membrane method will be the most promising one in this feild.
