Liquid with minimal CO2 solubility 2

[Ofer L.]

Hello,
I'm looking for any kind of liquid medium in which CO2 has minimal solubility at 25C and pressure around 70barg.
Currently CaCl2 aqueous solution seems to be the best candidate (~2 %w/w), is there any other recommended material with lower solubility of CO2?

Thanks,
Ofer

Though this compilation is not at 70barg, it may give you some indication of comparative trends:
