Abstract

鉄,コバルトフタロシア屯ン誘導体が酵素類似の機構で,悪臭成分と反応することを利用して,バイオミメティックな消臭機能を持つ消臭繊維を開発した.生体内の一連の酸化酵素が大気や食物を通じて生体内に入る種々の毒物を酸化し,解毒することに注目し,まず,これらの酵素の活性中心であるヘマトポルフィリンIXと類似の構造を持っ,Fe(III),Co(II)フタロシアニンのカルボン酸誘導体とそれらのポリマーを合成したこれらの錯体と高分子錯体によるoxidase,catalase,peroxidase,oxygenaseおよびその高分子系が,酵素と類似した触媒作用を示し,さらに天然物より優れた触媒能を有することを見いだした.<BR>次に,これらのフタロシアニン誘導体を各種高分子材料に担持し,複合化して種々の消臭素材を開発した.特に,多孔質,多非晶質レーヨンに担持したフタロシアニン誘導体により,チオール,アミンなどの悪臭成分の除去機構を速度論的に解析し,酵素類似の反応機構で除去できることを明らかにした.<BR>さらに,この消臭繊維を用い,寝たきり病人の病室,トイレ,下水処理場などの現場で分析試験を併用し,その効果の詳細な評価,検討を行った.その結果,悪臭の原因となる主成分はppbレベルのチオールなどであり,この消臭繊維により,空気中のこれら硫黄化合物を0.1ppb以下に除去できることを明らかにした.また,耐久性,耐洗濯性など実用的性能も優れていることがわかった.したがって,フタロシアニンを担持したレーヨン,ウール,綿などを工業化し,綿不織布,織物などに加工し,布団,カーペットなど多彩な消臭能を持つ商品開発を行った.

The odor removing fibers having biomimetic functions have been developed applying the enzymelike catalytic functions of iron (III) or cobalt (II) phthalocyanine (Fe (III)-, Co (II)-pc) derivatives and their polymers. The oxidoreductase role as antidote against poisonous substance invading the body by activating oxygen in the blood. We have studied the kinetics of model reaction of Fe (III)- or Co (II)-pc derivatives and their polymers, which have similar structure to active center, hematoporphirine IX, of oxidation-reduction enzymes. The Fe (III)- or Co (II)-pc derivatives and remarkably effective catalyst for the metal complexes. Next, various kinds of new odor removing materials by supporting Fe (III)-, Co (II) -octacarboxyphthalocyanines [M-oapc, M = Fe (III), Co (II) ] on various polymer materials and fiber have been developed.<BR>The kinetics of odor removing mechanism of Mt-oapc supporting on porous and amorphous enriched rayon stable fiber have been also investigated.<BR>It was found that the foul oder su bstances such as thiols, amines, etc. can be removed by the enzymelike reaction of Mt-oapc supporting on the rayon fibers. Further, the odor-removing abilities of these fibers by the room for bedridden patients, waste water treatment place and lavatory were evaluated. These results showed trace amount sulfur compounds which are main compound in odor were effectively removed less than 0.1 ppb using the fiber containing Mt-oapc. The fiber eliminated more quantity of the foul oder substances by 20 to 100 times than did activated carbon, and can withstand 50 times of washing.<BR>Applying these properties, new types of odor-removers such as mattress, quilt, blanket, wad, woven, and nonwoven materials produced from odor-removing fibers have been developed.
