B. Jose et al., Effect of phthalates on the stability and performance of AgBF4-PVP membranes for olefin/paraffin separation, CHEM COMMUN, (20), 2001, pp. 2046-2047
The presence of a phthalate in dry polymer membranes consisting of polyviny
lpyrrolidone (PVP) and AgBF4, AgBF4-PVP, provides long-term stability and b
etter performance for the separation of propylene/propane gas mixtures.
