    摘要: To improve the pervaporation performance of polyamide membrane, novel thin-film composite (TFC) polyamide membranes were prepared by interfacial polymerization of novel water-soluble 2,2’-dimethylbenzidine hydrodiamine (m-tolidine-H) and toluene-soluble trimesoyl chloride (TMC) on the surfaces of modified asymmetric polyacrylonitrile (mPAN) membrane. Effects of aqueous amine solution immersion time and polymerization time on the pervaporation performance through m-tolidone-H-TMC/mPAN composite membranes were investigated. The permeation rate decreases with increasing both aqueous amine solution immersion time and polymerization time for pervaporation separation of 9Owt% ethanol water mixture through the m-tolidone-H-TMC/mPAN membrane. The polyamide/mPAN composite membrane prepared by immersing 1 .5wt% aqueous m-tclidine¡EH solution for lOs and then contacting with 0.O5wt% TMC for l0s has the best pervaporation performance. The water concentration in permeate approaches 99wt% and a 2300 g/m2h permeation rate with a 90 wt% aqueous ethanol solution at 2500 was obtained.
