Abstract

본 발명은 유기수용액 분리용으로 적합한 유기 공중합체 투과증발막의 제조방법에 관한 것으로서, 좀 더 구체적으로 유기수용액에 함유된 물에 대해서는 높은 투과율을 나타내고 유기용제에 대해서는 낮은 투과율을 나타내어 유기 용제를 고순도로 분리해 낼 수 있는 유기수용액 분리용 폴리아크릴로니트릴 공중합체계 투과증발막의 제조방법에 관한 것이다.The present invention relates to a method for preparing an organic copolymer pervaporation membrane suitable for separating an organic aqueous solution, and more particularly, a high permeability for water contained in an organic aqueous solution and a low permeability for an organic solvent. The present invention relates to a method for producing a polyacrylonitrile copolymer-based pervaporation membrane for separation of an organic aqueous solution that can be separated.

본 발명에서는 아크릴로니트릴에 비닐모노머로서 아크릴산 또는 4 - 비닐피리딘을 사용하여 유화제를 사용하지 않는 에멀젼 종합법으로 폴리아크릴로니트릴 공중합체계 투과증발막을 제조하였다. 본 발명의 폴리아크릴로니트릴계 공중합체는 상기와 같이 유화제를 사용하지 않음으로 해서 유화제에 의한 고분자막의 오염을 제거할 수 있었으며, 제조시 중합 용액의 pH를 7로 조정함으로서 좋은 수율로 공중합체를 얻을 수 있었고, 또한 공중합체막의 분리성능을 최적화하기 위해 아크릴로 니트릴-아크릴산 공중합체의 경우 카르복실기를 55몰%정도까지 함유하며, 아크릴로니트릴 -4-비닐피리딘 공중합체막의 경우 피리딘기를 30몰%정도까지 함유함을 그 특징으로 한다.In the present invention, a polyacrylonitrile copolymer-based pervaporation membrane was prepared using an emulsion synthesis method using no acrylic emulsifier or acrylic acid or 4-vinylpyridine as a vinyl monomer. The polyacrylonitrile-based copolymer of the present invention was able to remove the contamination of the polymer membrane by the emulsifier by not using the emulsifier as described above, and by adjusting the pH of the polymerization solution to 7, the copolymer in good yield Acrylonitrile-acrylic acid copolymers contain up to 55 mole percent of carboxyl groups, and 30 mole percent of pyridine groups for acrylonitrile-4-vinylpyridine copolymer membranes in order to optimize the separation performance of the copolymer membrane. It is characterized by containing to the extent.
