Abstract
【解決手段】気相中の揮発性有機化合物、例えば、トルエン、キシレン等の芳香族炭化水素、n−ノナナール等の脂肪族アルデヒド類をメソポーラスシリカに吸着させ、これに紫外線を照射することによって、酢酸及び/又は二酸化炭素を含む分解物にまで光酸化分解することができる。例えば、p−キシレンの場合、これを4−メチルベンズアルデヒドと4−メチル安息香酸と4−ホルミル安息香酸と酢酸等に分解することができる。
【選択図】なし
Description
0.01gのMCM−41(平均細孔径2.7nm)を入れた開放サンプル瓶をテドラーバック内に置き、次に、このテドラーバック内にトルエンを入れた開放瓶を置き、テドラーバックを密封し、一晩、放置して、テドラーバック内の空気にトルエンを飽和させた後、テドラーバック内でサンプル瓶をミニナートバルブで栓をした。テドラーバックからサンプル瓶を取出して、40℃の恒温槽中に保持しながら、これに水銀−キセノンランプ(SII社製UV−1(200W)、以下、同じ)を用いて紫外線を24時間照射した。
メソポーラスシリカとしてMSU−H(平均細孔径7.1nm)を用いた以外は、実施例1と同様に処理し、実施例1と同様にして、光照射後の成分を分析した。ガスクロマトグラムを図2に示すように、光酸化分解物としてメチルベンズアルデヒドと安息香酸が生成した。
0.01gのMCM−41を入れた開放サンプル瓶をテドラーバック内に置き、次に、このテドラーバック内にp−キシレンを入れた開放瓶を置き、テドラーバックを密封し、一晩、放置して、テドラーバック内の空気にp−キシレンを飽和させた後、テドラーバック内でサンプル瓶をミニナートバルブで栓をした。テドラーバックからサンプル瓶を取出して、40℃の恒温槽中に保持しながら、これに水銀−キセノンランプを用いて紫外線を24時間照射した。
メソポーラスシリカとしてMSU−Hを用いた以外は、実施例3と同様に処理し、実施例1と同様にして、光照射後の成分を分析した。ガスクロマトグラムを図4に示すように、光酸化分解物として4−メチルベンズアルデヒドと4−メチル安息香酸と4−ホルミル安息香酸と酢酸が生成した。
実施例2において、揮発性有機化合物として、p−キシレンに代えて、n−ノナナールを用いた以外は、実施例2と同様に処理し、実施例1と同様にして、光照射後の成分を分析した。ガスクロマトグラムを図5に示すように、光酸化分解物として、酢酸が生成した。
500mL容量のサンプル瓶に酢酸を入れ、40℃で一晩、放置した後、その瓶内の酢酸を含む空気4mLを採取して、0.01gのMCM−41を入れた開放サンプル瓶内に注入し、このサンプル瓶を40℃の恒温槽中に保持しながら、これに水銀−キセノンランプを用いて紫外線を24時間照射した。実施例1と同様にして、光照射後の成分を分析したところ、酢酸は完全に光酸化分解されており、酢酸は検出されなかった。
0.01gのMCM−41を入れた開放サンプル瓶をテドラーバック内に置き、次に、このテドラーバック内に酢酸を入れた開放瓶を置き、テドラーバックを密封し、一晩、放置して、テドラーバック内の空気に酢酸を飽和させた後、テドラーバック内でサンプル瓶をミニナートバルブで栓をした。テドラーバックからサンプル瓶を取出して、40℃の恒温槽中に保持しながら、これに水銀−キセノンランプを用いて紫外線を24時間照射した。この後、サンプル瓶のヘッドスペースからガス成分を抜取り、MSガス分析装置(アネルバ社製四重極型M−100−QA−M)にて二酸化炭素量を測定した結果、0.59%であった。MCM−41に代えて、MSU−Hを用いた場合には、二酸化炭素量は0.66%であった。
0.01gのMCM−41を空気中、500℃で焼成した後、水を張ったデシケータ中に24時間放置したもの(含水率47重量%)を用いた。実施例1において、上記水分を含有させたMCM−41を用いて、p−キシレンを光酸化した以外は、同様にして、実施例1と同様にして、光照射後の成分を分析した。ガスクロマトグラムを図6に示すように、残存p−キシレンと共に、光酸化分解物として、4−メチルベンズアルデヒドと酢酸が生成した。
0.01gのMCM−41を入れた開放サンプル瓶をテドラーバック内に置き、次に、このテドラーバック内に酢酸を入れた開放瓶を置き、テドラーバックを密封し、一晩、放置して、テドラーバック内の空気に酢酸を飽和させた後、テドラーバック内でサンプル瓶をミニナートバルブで栓をした。テドラーバックからサンプル瓶を取出して、紫外線を照射することなく、暗所に24時間放置した後、実施例1と同様にして、サンプル瓶内の成分を分析したところ、酢酸のみが検出された。
MCM−41に代えて、ゼオライト5A(平均細孔径0.5nm)を用いた以外は、実施例2と同様に処理し、実施例1と同様にして、光照射後の成分を分析したが、光酸化分解物の生成は認められなかった。
MCM−41に代えて、ゼオライト13X(平均細孔径1.0nm)を用いた以外は、実施例2と同様に処理し、実施例1と同様にして、光照射後の成分を分析したが、光酸化分解物の生成は認められなかった。
