抄録
Asymmetric polyimide Kapton®membranes were made by casting a solution of 18 wt% polyamic acid and 5 wt% phenanthrane in dimethylacetamide. The fluxes of ethylbenzene and hexane obtained with the mixtures with CO2 were 1.2-1.4 times higher than those for pure solutes respectively. The measured separation factors, α (ethylbenzene/hexane), were 1.86 at 323K, 1.93 at 373K and 1.81 at 423K and found to be practically independent of the temperatures and the pressures.
