Abstract
β-Cyclodextrine/benzoic acid complex was prepared and reacted with cyanuric chloride(2,4,6-trichloro-1,3,5-trizine). Identification of complex formation and reaction was checked by FT-IR, UV-Vis, and EDX. By reacting this material with cotton fiber, the deodourant fiber was prepared. The deodourizing property was evaluated by the concentration changes of aqueous ammonia solution after flowing ammonia gas through the column filled with deodourant fiber prepared. The deodourzing property was increased with an increase of concentration of β-cyclodextrine unit in the fiber. In the case of β-cyclodextrine/benzoic acid complex, the deodourzing property was much increased, comparing with the β-cyclodextrine only. It was considered to be the binding of ammonia gas caused by benzoic acid in the complex.

포접(抱接) 기능을 가져 악취의 분리제거에 사용될 수 있을 것으로 보이는 β-시클로덱스트린 및 β-시클로덱스트린에 벤조산을 포접시킨 물질(β-시클로덱스트린/벤조산 포접체)에 시아누르산 염화물을 반응시켜 클로로트리아진 유도체를 제조하고, 이를 면섬유와 반응시켜 새로운 소취기능성 섬유를 제조하였다. 포접체의 형성은 적외선 분광분석 및 가시-자외선 분광분석기를 사용하여 확인하였으며, 반응기의 도입은 EDX로 확인하였다. 소취성능은 제조한 소취기능성 섬유를 컬럼에 채우고, 암모니아 기체를 흘려 보냈을 때 빠져나온 암모니아를 물에 용해시킨 용액의 농도를 0.1N 염산으로 적정하여 평가하였다. 섬유에 부착된 β-시클로덱스트린 단위가 증가할수록 소취성이 증가하였으며, β-시클로덱스트린에 벤조산을 포접한 경우에 소취성이 보다 증가하였다. 이는 포접체에 존재하는 벤조산과 암모니아의 결합 때문이라고 생각되었다.
