Effect of phthalates on the stability and performance of AgBF4–PVP membranes for olefin/paraffin separation
Abstract
The presence of a phthalate in dry polymer membranes consisting of polyvinylpyrrolidone (PVP) and AgBF4, AgBF4–PVP, provides long-term stability and better performance for the separation of propylene/propane gas mixtures.
