Porous liquid and methods of making and using the same

The porous liquid of 1, wherein the liquid film includes at least one of:

• an amine;
• an alkali metal hydroxide;
• glycol;
• an enzyme;
• a thickness from the bottom of the roughness or the texture to the top surface of the liquid film no greater than 1400 μm;
• or
• a combination thereof.

A method of performing a liquid-based extraction, the method comprising:

• contacting (1) a porous liquid comprising a high surface area solid and a liquid film, wherein the high surface area solid has a surface area of greater than 0.001 m2/g, and wherein the high surface area solid includes wool, glass, glass wool, polyethylene wool, quartz wool, fibers, or a combination thereof, such that:
• i) the liquid film coats at least 30% of the surface area of the high surface area solid,
• ii) the porous liquid has an S/V greater than 180 m−1 wherein S is the surface area of the high surface area solid and V is the volume of the high surface area solid, and
• iii) the performance index (PI) is at least 150 m−1;
• and
• (2) a fluid that is immiscible with the liquid film such that a liquid-fluid interface is produced, wherein at least one substance in the fluid is extracted by the liquid film resulting in mass transfer across the liquid-fluid interface.

A method of performing an enzymatic reaction, the method comprising:

• contacting (1) a porous liquid enzyme comprising a high surface area solid and a liquid film comprising an enzyme, wherein the high surface area solid has a surface area of greater than 0.001 m2/g, and wherein the high surface area solid includes wool, glass, glass wool, polyethylene wool, quartz wool, fibers, or a combination thereof, such that
• i) the liquid film coats at least 30% of the surface area of the high surface area solid,
• ii) the porous liquid enzyme has an S/V of greater than 180 m′ wherein S is the surface area of the high surface area solid and V is the volume of the high surface area solid, and
• iii) the performance index (PI) is at least 150 m−1;
• and (2) a fluid comprising at least one substrate for the enzyme in the liquid film, wherein the fluid is immiscible with the liquid film such that a liquid-fluid interface is produced, and wherein contacting the fluid and the porous liquid enzyme results in at least one of the catalysis of the substrate, mass transfer of the substrate across the liquid-fluid interface, or both.
