    Abstract: Provided is a method for separating a specific gas from a raw gas using a gas separation membrane module. The module includes a gas separation membrane element enclosed in a housing. The element includes a gas separation membrane including a hydrophilic resin composition layer for selectively allowing for the permeation of the specific gas. The method includes the steps of: preparing the module; increasing pressure in an interior of the module; increasing a temperature in the interior; and feeding a raw gas to the interior. The hydrophilic resin composition layer of the module prepared in the preparation step is adjusted to contain moisture, and a moisture content thereof is an amount that allows an equilibrium relative humidity at a temperature of 23°C of a gas phase portion in the housing to be greater than or equal to 10%RH. The raw gas feeding step is performed after the preparation step. The pressure increase step and the temperature increase step are performed after the preparation step and before the raw gas feeding step.

    Abstract: Provided is a method for separating, from a raw gas containing a specific gas, the specific gas using a gas separation membrane module. The gas separation membrane module includes a housing and a gas separation membrane element enclosed in the housing. The gas separation membrane element includes a gas separation membrane including a hydrophilic resin composition layer for selectively allowing for permeation of the specific gas. The method includes the steps of: increasing pressure in an interior of the gas separation membrane module; increasing a temperature in the interior of the gas separation membrane module; and feeding a raw gas to the interior of the gas separation membrane module in that order.

    Abstract: A process for producing 4-hydroxymethyl-2,3,5,6-tetrafluorotoluene by subjecting a 4-hydroxymethyl-2,3,5,6-tetrafluorobenzyl halide to contact with hydrogen in the presence of an alcohol solvent having 1 to 3 carbon atoms and palladium on carbon, wherein the temperature of a mixture of the alcohol solvent having 1 to 3 carbon atoms and the palladium on carbon is kept at 15°C or lower until initiation of the contact of the 4-hydroxymethyl-2,3,5,6-tetrafluorobenzyl halide with the hydrogen.
