Description
廃棄空気精製設備における溶剤吸着に加えて、本発明のエーロゲルは、気相から吸着する必要がある、公知のすべての用途に使用することができる。その例は、気体混合物の分離および気体からの不純物の吸着である。不純物が重要である場合、これらの不純物は、例えば酸化窒素、酸化硫黄、一酸化炭素、アンモニアまたは有機ガスの様な気体状不純物である。不純物は、蒸発した液体またはガス流の中に取り込まれた液体の滴でもよい。親水性変性したエーロゲルも、気体の乾燥に、すなわち水の除去に使用することができる。
本発明により使用するエーロゲルの吸着能力が消耗し尽くした場合、そのエーロゲルは公知の方法により再生することができる。例えば、吸着された物質は熱により除去することができる。他の気体、例えば蒸気、による除去も可能であり、適当な方法は当業者には公知である。
本発明のエーロゲルはさらに、複数の液相から吸着させるための吸着剤として使用することができる。その際、「液相」の表現は、均質な溶液、エマルジョン、分散液、溶液中に気体を含む液体、および類似の混合物を含むことができる。その場合、液体はキャリヤー相として作用し、そこから物質をエーロゲルにより吸着する。
含水物質の吸着 廃水から有機化合物を選択的に吸着することを立証するために、ベンゼン、フェノール、トルエン、1,2−ジクロロエタンおよびp−クロロフェノールを、芳香族および/または塩素化炭化水素の群の例として選択した。これらの化合物を様々な水中濃度で、25℃でエーロゲルと接触させ、エーロゲルの吸着量を測定した。これらの試験は振とう容器中で行なった。DE−A−4342548明細書に記載されている例に準じて製造した6gの疎水性エーロゲル(粒子径0.1mm、比内部表面積約500平方m/g)を、精製すべき水性混合物と振とう容器中で接触させた。平衡に達するまで最長2時間を要した吸着時間の前後の液体濃度を測定することにより、吸着された物質の量を物質収支から計算することができた。結果を図1に示す。
抗生物質の吸着
製造の際に生じる発酵溶液から製薬活性成分を処理する例として、抗生物質セファロスポリンC(CPC)の吸着を試験した。製造中、CPCは発酵溶液1リットルあたり数グラムの濃度で生じ、この溶液からできるだけ注意深く分離する必要がある。これに関して、膨大な数の他のアミノ酸、塩、糖、その他の内容物に加えて、溶液は生物合成の副生成物としてデスアセチル−CPC(D−CPC)
Claims (3)
- ベンゼン、フェノール、トルエン、1,2−ジクロロエタンおよびp−クロロフェノール、およびそれらの組み合わせからなる群から選択される化合物を含む廃水を、シリル化によって疎水性にされた、ケイ素または金属の酸化物のエーロゲルと、前記化合物を吸着するのに十分な時間接触させ、その後、前記エーロゲルを前記廃水から分離し、次いで前記化合物を前記エーロゲルから分離するものであり、前記エーロゲルが、窒素吸着を使用するBET測定で100〜1000平方メートル/gの内部表面積を有する、ことを特徴とする廃水を精製する方法。
- 前記エーロゲルが、さらなるキャリヤー物質を含まない、請求項1に記載の精製方法。
- セファロスポリンC、デスアセチルセファロスポリンC、およびデスアセトキシセファロスポリンCを含む、セファロスポリンCの製造において生成する水性発酵液体からセファロスポリンCを分離する方法であって、前記水性発酵溶液をシリル化によって疎水性にされた、ケイ素または金属の酸化物のエーロゲルと、前記セファロスポリンCを吸着するのに十分な時間接触させ、その後、前記エーロゲルを前記水性発酵溶液から分離し、次いで前記セファロスポリンCを前記エーロゲルから分離するものであり、前記エーロゲルが、窒素吸着を使用するBET測定で100〜1000平方メートル/gの内部表面積を有する、ことを特徴とする方法。
