ABSTRACT:
A diaphragm for gas-liquid contact comprising a membrane having two surfaces, at least one surface of the membrane is hydrophilic and surfaces of micropores present in the membrane are hydrophobic. The diaphragm is used in contact apparatus in which a liquid is contacted with the hydrophilic surface of the membrane and a gas is contacted with the other surface. The diaphragm is used in a process for producing a liquid containing a gas dissolved therein, which comprises introducing a liquid into contact with the hydrophilic surface of the membrane and a gas into contact with the other surface of the membrane and having the gas pass through the membrane and dissolve in the liquid.
