Abstract: The present invention provides a porous non-metallic material including a material body, the material body is composed of pore cavities and cavity walls formed by surrounding the pore cavities in three-dimensional space. The pore cavities are uniformly distributed, and each pore cavity is three-dimensionally interconnected. The pore cavities are uniformly distributed means that the pore cavities are uniformly distributed under any unit-level volume on the porous material. The present invention provides a specific and clear measurement method for pore cavities distribution uniformity of the porous material, that is, the pore distribution uniformity of the porous material and the hierarchical structure thereof is measured on the scale of the small unit-level volume. Such porous structure is highly uniform, thereby ensuring the uniformity of the properties of the porous material.

A liquid containing at least one member selected from the group consisting of a fluorinated compound represented by the following formula (1) and a fluorinated compound represented by the following formula (2) is held at a heating temperature of at most 150°C and distilled:

         R F OR 1 COOH     (1)

         R F OR 1 COOR 2      (2)


R F is a linear or branched monovalent fluoroorganic group which may have an etheric oxygen atom in its main chain, R 1 is a linear or branched bivalent organic group, and R 2 is a linear or branched monovalent organic group. Further, the liquid is a liquid obtained from any of a waste liquid after an aqueous emulsion of a fluoropolymer is coagulated and the fluoropolymer is separated, an aqueous liquid obtained by cleaning an exhaust gas in a step of drying and/or a step of heat treatment of the separated fluoropolymer, and a liquid obtained by cleaning an anion exchange resin which has been brought into contact with the waste liquid or an aqueous dispersion obtained from the aqueous emulsion of the fluoropolymer, with an alkaline aqueous solution.
