Abstract(#br)A composite polydimethylsiloxane (PDMS)/polyamide (PA) membrane was synthesized and sorption, diffusion and permeation of C 3 H 8 , CH 4 and H 2 were studied both in pure and mixed gas experiments. Pure gas experiments showed that, increasing transmembrane pressure increases solubility, permeability and diffusivity coefficients of heavier gases, C 3 H 8 , while does not affect or slightly decreases those of lighter ones, CH 4 and H 2 .

Abstract(#br)Vapor permeation through dense membrane is regarded as an effectively way to separate volatile organic compounds (VOC) from industrial gas stream. This study proposes a new method to get the solubility and diffusivity of pure VOC vapor in dense membrane. C 5 H 12 , C 6 H 14 and C 7 H 16 were selected as sample VOC components to conduct newly developed sorption experiment with polydimethylsiloxane (PDMS) membrane.

Solubility and diffusivity of liquids for food and pharmaceutical applications in crosslinked polydimethylsiloxane (PDMS) films: I. Experimental data on pure organic components and vegetable oil

由 ty10086 提交于 周四, 08/26/2021 - 13:28
Abstract(#br)The solubility and diffusivity of several liquid species in crosslinked polydimethylsiloxane (PDMS) films were determined with a gravimetric method at 35\u003cce:hsp sp=\"0.25\"/\u003e°C. The series of liquids considered includes alkanes (from n-C 5 to n-C 18 ; cyclo-C 6 ), water, acetone, alcohols (ethanol, 1-propanol, 1-butanol, iso-butanol, tert-butanol, 1-pentanol, 1-hexanol), terpenes (squalene, limonene, linalool, geraniol) and edible oils with different oleic acid contents.
